Lexapro can calm you
and help you concentrate, but it doesn't sound like it's working for you. Don't stop this medication abruptly due to withdrawal, instead seek out a psychiatrist for a proper diagnosis and he can refer you to the necessary therapist or psychologist. Between medication and therapy, you can see results rather quickly.
