Learn the Language of Mental Health Easily

Mental health affects how we think, feel, act, and manage daily life. Just like physical health, our emotional and mental well-being is a crucial part of living a balanced and happy life. Whether it's handling stress at work, managing relationships, coping with loss, or simply maintaining a positive outlook, mental health plays a key role.

Understanding mental health is important because it empowers us to take better care of ourselves and others. Often, people struggle because they don't have the words to explain what they're feeling. Learning common mental health terms can bridge that gap, making it easier to seek help, offer support, or simply understand what's happening inside our minds.

This guide is designed to explain mental health terms in simple language so that everyone can understand. Knowledge is the first step toward healing and growth, and this dictionary is here to make that journey easier for you.

1. Types of Mental Health Disorders

Addiction

Addiction is when someone can’t stop doing something harmful even if they want to. You find yourself scrolling on social media for hours every night even though you know it's affecting your sleep and mood and you can't seem to stop. This could be a form of technology addiction. Examples are substance addiction (like alcohol, drugs) and behavioral addiction (like gambling, internet, or shopping).

Bipolar Disorder

Bipolar disorder is when a person’s mood changes a lot from feeling extremely happy and energetic to feeling very sad and tired. One week someone might feel like they can do anything (very high energy) and the next week they might not want to get out of bed (very low energy). Examples are Bipolar I Disorder, Bipolar II Disorder, and Cyclothymic Disorder (milder mood swings).

Depression

Depression is a mental illness where a person feels very sad, empty, or hopeless for a long time. It’s more than just having a bad day. If someone loses interest in activities they once enjoyed and feels tired all the time for weeks, they might be facing depression. Examples are Major Depressive Disorder, Persistent Depressive Disorder (dysthymia), and Seasonal Affective Disorder (SAD).

Obsessive Compulsive Disorder (OCD)

OCD is when a person has unwanted thoughts (obsessions) and feels the need to do certain actions repeatedly (compulsions) to feel better. Washing hands again and again because you feel they are dirty, even when they are clean, is a sign of OCD. Examples are contamination OCD (fear of germs), checking OCD (repeatedly checking things), and intrusive thoughts OCD.

Phobia

A phobia is an intense fear of something that usually isn’t very dangerous. Being extremely scared of heights, spiders, or public speaking can be a phobia. Examples are specific phobias (like fear of heights or spiders), social phobia (fear of being judged), and agoraphobia (fear of crowded places).

Post Traumatic Stress Disorder (PTSD)

PTSD is when a person keeps feeling scared or upset long after experiencing a scary event. A soldier who hears fireworks and gets scared because it reminds them of war might have PTSD. Examples are normal stress response, acute PTSD (symptoms within 3 months), chronic PTSD (longer lasting), and complex PTSD (caused by repeated trauma).

2. Symptoms and Feelings

Anxiety

Anxiety is when you feel very worried, nervous, or scared, even when there’s no real danger. Feeling butterflies in your stomach before a presentation is normal. But if you feel like that all the time, even without a reason, it could be anxiety. Examples are Generalized Anxiety Disorder (GAD), Social Anxiety Disorder, Panic Disorder, and Specific Phobias.

Emotional Regulation

Emotional regulation means learning how to manage your feelings instead of letting them control you. Taking deep breaths instead of yelling when you’re angry shows emotion regulation. Examples are healthy regulation (like calming yourself down or expressing feelings constructively) and dysregulation (like sudden outbursts or shutting down emotionally).

Loneliness

Loneliness is feeling sad because you are alone or don’t feel connected to others. Even if you are surrounded by people, you can still feel lonely if you don't feel understood. Examples are emotional loneliness (missing close connection) and social loneliness (lacking a wider social network).

Mood Swings

Mood swings are quick and strong changes in how you feel -  happy one minute, angry or sad the next. Laughing with friends and then suddenly crying without a clear reason could be mood swings. Examples are normal mood swings (due to daily stress) and extreme mood swings (seen in conditions like Bipolar Disorder).

Negative Thinking

Negative thinking means focusing only on bad things, even when good things are happening too. You make a small mistake in a presentation and immediately start thinking, "I'm useless. I'll never succeed," even though overall the presentation went well. Examples are all-or-nothing thinking (seeing things as black or white), catastrophizing (expecting the worst), and overgeneralization (believing one bad event means everything is bad).

Panic Attack

A panic attack is a sudden feeling of intense fear that causes physical symptoms like a racing heart, sweating, or difficulty breathing. Feeling like you can’t breathe or are going to faint even though you're physically okay can be a panic attack. Examples are unexpected panic attacks (no clear cause) and expected panic attacks (triggered by specific situations).

Stress

Stress is your body’s reaction to a challenge or demand. It can be good (like feeling excited before a game) or bad (like feeling overwhelmed with homework). You have a tight project deadline at work, and you start feeling overwhelmed, your heart beats faster, and you can't focus properly. Examples are acute stress (short-term stress like before an exam), episodic acute stress (frequent short-term stress), and chronic stress (long-term ongoing stress).

Suicidal Thoughts

Suicidal thoughts are when someone thinks about ending their own life because they feel hopeless. If someone feels like this, it’s important to talk to a trusted adult, teacher, counselor, or call a helpline immediately. Examples are passive suicidal thoughts (wishing you were dead without plans) and active suicidal thoughts (thinking about how you might end your life).

Tension

Tension is a feeling of tightness, worry, or pressure in your body or mind. You and your roommate had an argument in the morning. Even after reaching office, you feel a heavy, uncomfortable feeling in your chest, that’s emotional tension. Examples are physical tension (tight muscles, headaches) and emotional tension (feeling mentally stretched or irritable).

Trauma

Trauma is an emotional response to a terrible event like an accident, natural disaster, or abuse. Someone who survives a car crash might feel scared of driving again because of trauma. Examples are acute trauma (single stressful event), chronic trauma (ongoing stress like abuse), and complex trauma (multiple traumatic experiences over time).

3. Therapies and Treatment Approaches

Coping Mechanisms

Coping mechanisms are ways you deal with tough situations or emotions. Some are healthy (like exercising) and some are unhealthy (like avoiding problems). Talking to a friend when you’re upset is a healthy coping mechanism. Examples of conflict resolution are active listening, compromise, mediation, negotiation, and setting clear boundaries.

Conflict Resolution

Conflict resolution is the skill of solving disagreements peacefully. Two coworkers having different opinions about a project can talk it out respectfully and find a solution that’s conflict resolution. Examples of grounding techniques are focusing on your breathing, holding an ice cube, describing objects around you, and listening to surrounding sounds.

Grounding

Grounding is a way to calm yourself when you feel scared, anxious, or disconnected by focusing on what’s happening around you right now. Touching a cold glass of water, listening to sounds, or counting things you see are grounding techniques.

Mindfulness

Mindfulness means paying full attention to what you are doing in the present moment without worrying about the past or future. When you eat your lunch slowly and enjoy every bite without looking at your phone, that's mindfulness. Examples of grounding techniques are focusing on your breathing, holding an ice cube, describing objects around you, and listening to surrounding sounds.

Positive Affirmations

Positive affirmations are kind and encouraging sentences you say to yourself to build confidence and positivity. Examples of positive affirmations are saying "I am enough," "I can handle this," "I am worthy of love," and "Every day is a new beginning."

Therapy

Therapy is when you talk to a trained professional (a therapist) to help you understand and solve emotional problems. Just like you visit a doctor when you have a fever, you can visit a therapist if you're feeling sad or stressed all the time. Examples of therapy are cognitive behavioral therapy (CBT), talk therapy, art therapy, group therapy, and trauma-focused therapy.

4. Mental Health Professionals

Counselor

A counselor is someone you can talk to about your problems, and they help you find ways to feel better. After struggling with relationship problems, you decide to visit a counselor who listens to you without judging and helps you find ways to communicate better with your partner. Examples of counselor are school counselors, grief counselors, and relationship counselors.

Psychiatrist

A psychiatrist is a doctor who can diagnose mental illnesses and also prescribe medicines. If someone has severe depression, a psychiatrist might give them medicines to feel better, along with therapy. Examples of psychiatrist are general psychiatrists, child psychiatrists, and addiction psychiatrists.

Psychologist

A psychologist studies the mind and helps people solve emotional or mental problems through talking and understanding feelings. If someone can’t sleep because of fear or sadness, a psychologist can help them figure out why. Examples of psychologist are clinical psychologists, counseling psychologists, and forensic psychologists.

5. Chemical Messengers of the Brain

Adrenaline

Adrenaline is a hormone that rushes through your body when you're scared, excited, or in danger. It makes your heart beat faster and gives you extra energy to act quickly. If you're about to give a big speech at a conference. Your heart races, your hands sweat, and you feel super alert, that's adrenaline kicking in to prepare your body for action. Examples of adrenaline rush are feeling excited before a speech, jumping suddenly at a loud noise, or escaping danger.

Cortisol

Cortisol is a hormone made by your body when you are stressed. It helps you react quickly in tough situations like if you see a dog chasing you, cortisol gives you the energy to run fast! But if cortisol stays high for too long (because of constant stress), it can make you feel tired, anxious, or even sick. Let’s say, after an intense argument with your boss, your body releases cortisol, the "stress hormone", making you feel jittery, anxious, and even giving you a headache. Examples of cortisol triggers are work deadlines, arguments, and poor sleep.

Dopamine

Dopamine is a "feel-good" chemical made by your brain. It plays a big role in making you feel happy, motivated, and excited, especially when you achieve something or get a reward. When you complete a major project and get praised by your manager, you feel proud and energized, that's dopamine, the "reward chemical," lifting your mood. Examples of dopamine release are finishing a task, eating your favorite food, or getting likes on social media.

Serotonin

Serotonin is another important chemical in the brain that helps control your mood, sleep, and appetite. It keeps you feeling calm and balanced. Low serotonin levels are linked to feeling sad or depressed. Going for a walk in the sunlight can naturally boost your serotonin and make you feel better. Examples of serotonin boosters are sunlight exposure, exercise, and eating bananas or eggs.

6. Self-Care and Coping Strategies

Boundaries

Boundaries are limits you set to protect your mental and emotional space. Your coworker keeps messaging you late at night about work. You politely tell them you won't be responding to work texts after 7 PM. Setting this limit is creating a healthy boundary. Examples of boundaries are saying no to extra work, not responding to texts after hours, or limiting family interference.

Gratitude

Gratitude means feeling thankful for the good things in your life. Being grateful for your family, good health, or a sunny day can lift your mood. Examples of gratitude are saying thank you, keeping a gratitude journal, or acknowledging small blessings.

Journaling

Journaling is the habit of writing down your thoughts, feelings, and experiences to better understand yourself and manage emotions. After a stressful day at work, writing in a journal can help you clear your mind and feel calmer. Examples of journaling are writing your thoughts daily, tracking moods, or listing things you're grateful for.

Non-Violent Communication

Non-Violent Communication is a way of talking and listening that focuses on being respectful, understanding, and honest without blaming or hurting others. Instead of shouting during a disagreement, you calmly say how you feel and what you need without attacking the other person. Examples of non-violent communication are using “I feel” statements, active listening, and avoiding blame.

Self Care

Self-care means doing things that help you stay mentally, emotionally, and physically healthy. Sleeping well, eating healthy, talking to a friend, or even taking a break to relax are all types of self-care. Examples of self-care are taking naps, eating nutritious meals, and spending time alone.

Support Group

A support group is a safe space where people with similar struggles share their experiences and help each other. There are support groups for people dealing with grief, addiction, anxiety, and more. Examples of support groups are AA meetings, grief circles, and online depression communities.

Support System

A support system is a group of people you can rely on when you need help or advice. Friends, family, teachers, or counselors can be part of your support system. Examples of support systems are friends, family members, therapists, or mentors.

Work-Life Balance

Work-life balance means having enough time for work, family, rest, and fun, so no part of your life suffers too much. Leaving the office on time to have dinner with family is part of good work-life balance. Examples of work-life balance are having weekends off, using vacation time, and avoiding work emails at night.

7. Crisis and Emergency Terms

Hostile Work Environment

A hostile work environment is when harassment, bullying, or discrimination at work is so bad that it makes it hard for someone to do their job.

Examples of hostile work environment are being yelled at often, constant sarcasm, or exclusion from meetings.

Suicide

Suicide is when someone ends their own life because they feel deeply overwhelmed, hopeless, or trapped. For example, a person dealing with ongoing emotional pain or serious problems might believe there’s no other way to escape their suffering. Examples of suicide risk signs are giving away belongings, talking about death, or withdrawing from loved ones.

Workplace Bullying

Workplace bullying is when someone at work regularly treats you badly like making fun of you, insulting you, or trying to make you look bad. If a boss always yells at one employee for mistakes but ignores the same mistake by others, that's workplace bullying. Examples of workplace bullying are public humiliation, gossiping, or blocking someone's work progress.

Workplace Stress

Workplace stress is the feeling of being overwhelmed, worried, or tense because of job pressures. If you have too many tasks and too little time to complete them, you might feel workplace stress. Examples of workplace stress are tight deadlines, unclear roles, or a toxic boss.
