Teen Mental Health

Being a teenager is hard. You're under stress to be liked, do well in school, get along with your family, and make big decisions. You can't avoid most of these pressures, and worrying about them is normal. But feeling very sad, hopeless or worthless could be warning signs of a mental health problem.

Mental health problems are real, painful, and sometimes severe. You might need help if you have the signs mentioned above, or if you:

  • Often feel very angry or very worried
  • Feel grief for a long time after a loss or death
  • Think your mind is controlled or out of control
  • Use alcohol or drugs
  • Exercise, diet and/or binge-eat obsessively
  • Hurt other people or destroy property
  • Do reckless things that could harm you or others
  • Feel depressed (sad and hopeless)

Mental health problems can be treated. To find help, talk to your parents, school counselor, or health care provider.
