An intense fear of throwing up, missing school, your grades slipping,
panic attacks, anger, stress and depression. The
Lexapro will help with some of that, but I believe you have a great deal of emotional baggage that a therapist trained to deal with young people could help you with very successfully. The pills will help you feel better, but they won't fix your problem. And your problem IS fixable.
Please discuss therapy with your parents or another trusted adult.
