I'm 16 and had that almost exact same problem. I went to see a derm who prescribed me Clindamycin but that was only slightly helpful, I went back and he gave me what I think is called Micro-Retin A (just a lower dose of Retin-A) And told me to put that on and then dab on the Clindamycin. I ended up using way to much and I got a chemical burn all over my forehead, which was horrible. I don't recommend you do that but if you use those two products it could be really helpful if you don't have very sensitive skin. (Btw I'm totally acne free after my burn healed, thank god for Vitamin E) I also found the AcneFree system really good. I hope I could help somewhat :)
