Acne Prone Skin for Women/Needing Advice. HELP?

Well going on 7 years now I have suffered with awful acne which has lead to scarring. It is embarring and has ruined my self-esteem. I hate leaving the house :( I have seen several dermatologists and I have been put on antibiotics which they made improvements but the second I get off them the break-outs come back. One antibiotic I was on was turing my teeth and gums grey so I have to discontinue the pill and just had to deal with the break-outs. I have terribly oily skin/hair. I have to wash my hair everday. I also have back acne. I don't know what to do. Ive spend so much money on Dr's/creams/make ups Im currently using Bare Minerals which has worked for me but Im noticing its not working for me like it used to. I have a DR appt in 2 weeks to figure out whats going on. I had a tubal done last April didn't have my monthly for a year and as soon as, I started my periods my face broke up like crazy even when im not on my monthly (TMI) but im just trying to get to the root of the problem. NO one else in my family has this problem like I do? What makeup would you recommend and what is left to do? I hate having to suffer its hard to have a social life with this problem. Im sure with people with this problem knows how I feel. Sorry for all this INFO but I just need some HELP n some FeedBack!! ThAN KS!!!
