bb/fbo [cleanse/champex help]

I've been suffering from bb and fbo for a year and a half now and I need help. I mostly suffer from bb. I'm a senior in high school. I read about champex here and I ordered some to try it. I was wondering if the champex will work alone or is a cleanse recommended before I take champex? Does anyone know a list of possible cures for this? I don't know the actual smell of it but I know I stink up the WHOLE classroom. I hear people making comments and the smell changes depending on what I eat. Can anyone recommend me something that might cure me? This has gotten me severely depressed and I've turned into a hermit. Everyday I watch my life pass me by, I can't live like this. Lost all my friends and I'm mocked everyday, can't even focus on my school work. I just want my life back, please help.
