My boobs are too big...?

So, I'm 15, but I've been a size 34, 36D for a while now. Honestly, I HATE them. They're too big.. At my school, it seems like all the girls have either absolutely nothing, or just barly a bump, then I look at myself in the mirror and, ugh. Its a pain. Is there any way to make them smaller without surgery? Or atleast get them to stop growing!?
