(background info: i'm 15)

i used to be on Lexapro until I decided to stop a few months ago. It's helped my self esteem a bit; made me feel a tiny bit normal, you know? i understand that medicine can help you, but i didn't like feeling like i needed it...
however, this hasn't done much good for my anxiety and agoraphobia/depression. things at school are too loud and too bright...it's harder to deal with. but is that worth dealing with if i have a shred of dignity left?
i understand the benifits of medicine and i respect anyone who takes it- really, who am i to judge anyone? but i still feel bad when im on it. and i feel like the medicine i was taking wasn't even working as well as it could have.
i stopped going to my therapist, and have pretty much no sort of theraputic help in a few months.

any imput? im just really confused and i dont know what to do. each day is getting harder to deal with, and im tired of this constant headache..
