Chapter 5: Mental and Emotional Problems
Lesson 1 — Mental Disorders
What Is a Mental Disorder?
A mental disorder is an illness that affects a person's thinking, feelings, or behavior to the point where it interferes with normal functioning. Mental disorders are medical conditions — they have biological, psychological, and social causes, just like physical diseases.
Common Mental Disorders in Teens
Anxiety Disorders
Excessive, persistent fear or worry that interferes with daily life. Includes generalized anxiety, panic disorder, social anxiety, and phobias.
Depression
Persistent sadness, loss of interest, low energy, and hopelessness lasting more than two weeks.
ADHD
Difficulty with attention, impulse control, and sometimes hyperactivity. Very common and highly manageable with the right support.
Eating Disorders
Unhealthy relationships with food and body image, including anorexia, bulimia, and binge eating disorder.
PTSD
Post-traumatic stress disorder develops after experiencing or witnessing a traumatic event.
OCD
Obsessive-compulsive disorder involves recurring, unwanted thoughts and repetitive behaviors.
Lesson 2 — Depression and Anxiety
Depression and anxiety are the two most common mental health issues among teenagers. Understanding them — what they look like, what causes them, and how they are treated — is essential health literacy.
Warning Signs of Depression
- Persistent sadness, emptiness, or hopelessness
- Loss of interest in activities once enjoyed
- Changes in sleep (too much or too little)
- Changes in appetite or weight
- Difficulty concentrating, making decisions
- Fatigue or loss of energy nearly every day
- Feelings of worthlessness or excessive guilt
Warning Signs of Anxiety
- Constant worry that is hard to control
- Physical symptoms: racing heart, sweating, trembling
- Avoiding situations that trigger fear
- Trouble sleeping due to worry
- Irritability and difficulty concentrating
Lesson 3 — Suicide Prevention
Suicide is the second leading cause of death for people aged 10–34 in the United States. It is preventable. Most people who consider suicide do not want to die — they want the pain to stop. Knowing the warning signs and how to respond saves lives.
Warning Signs
- Talking about wanting to die or having no reason to live
- Giving away prized possessions
- Saying goodbye to people as if they will not see them again
- Sudden calmness after a period of deep depression
- Researching methods of self-harm
Lesson 4 — Getting Help
Treatment works. Most people with mental health conditions improve significantly with the right support. The most important step is reaching out.
