Please Help me!? (Acne??)?

I'm 16 years old, and I started getting acne when I was about 11 or 12. I HATE IT! It ruins my life, and it ruins my confidence. I usually cover it up with a little makeup (I know, it clogs pores and stuff but it's sooo hard to walk out the door everyday without covering it up. It drains you of ANY confidence you ever had). I've been using clearasil, and it seems to be working ok, but I still get mean breakouts, especially around my time of month, I breakout and then it lingers around for a few weeks. I've tried many things before, and I've even talked to my doctor about it. He prescribed Retin-A-Micro to me, but it dried out my skin and created more pimples. Will they ever go away? I started my periods at 12, and they are normal and regular now, but the pimples still come and breakout my face. HELP ME?! I'm so tired of this now, I don't know what to do. I've tried acnefree, which is like another form of Proactive, and that literally burnt my face after a few weeks of use. My skin is combination/oily skin. Please help me! I'm out of ideas!
