I've asked for several opinions and i'm only getting worse, please listen to what I have to say.. i hope someone can give me a suggestion.

I'm 16, and the first week of september i had a minor panic attack at school, and i still went a fair bit but i started to avoid the first half of school and only go to the second half which is placed outside of my highscool, now i don't go to either because i'm to afraid of panicking, due to a full out panic attack. I went to mcdonalds the other day, made it two bites into my burger and had to leave, i can't stay anywhere. I was prescribe celexa for depression and never took it because i thought it wouldn't help, and then asked for ativan and they wouldn't give it to me because it's addicting, and then they gave me something else that i don't know what it's called but it's supposed to work faster, and i ended up not being able to take it because it's to big. I wish I was allowed to admit myself into the hospital, but you have to pretty much be trying to kill yourself to do that. I feel lost, feel anxiety, panic and i'm pretty sure i'm just getting really depressed because I can't go out. I know it's all in my head but I can't get over it, i've been to lots of counselors (the only form of mental health there is in this area) and the last one I had I didn't like from the beginning but I thought i'd try because I was desperate but she isn't any help so I stopped seeing her. I can't deal with myself anymore I barely know what day it is half the time.. i'm afraid of what i'm going to do to myself if I don't do something, i'm so scared of everything and it seems no one can help me. Please make a suggestion, I don't know where to turn..
