Skin problems

I have horrid skin, e.g. I have acne 
Ever morning I look in the mirror and want to cry with how disgusting I feel. I think I'm quite an attractive person, but that's only when I pile makeup on and cover my skin. The way my skin is determines what I will do that day, if it's bad I'll cancel on whoever I am going out with, I won't even leave my room. I wish there was something I could do to get rid of it. It started when I was about 14 and has gotten so bad, now I'm 17. I am currently on lymaciline/tetracycline and use benzoyl peroxide cream. I've been to ever spectrum of intensity, to points where the whole of my face was burnt and peeling from the strength of the cream, to some that don't do anything. Will someone help me and tell me how they go over their acne, as I'm going to the doctors again in a few days. Anything to suggest or take?
