Advice? Options? I am struggling

Im 15 and have been on and off the pill because my periods are horrible with cramps, nausea, vomiting, very heavy bleeding and I try to manage my acne. Speaking with my obgyn I have tried many different pills. The pill gives me mood swings, headaches and most of the time I feel depressed. I want to get off of birth control but feel like I can't because my periods effect school and my everyday life, I also worry my acne will come back very bad. Any advice?
