Big Boobs

Hi! I'm 15 and I have really big boobs. I took a prescribed anti-depressant with an unknown side effect about a year ago, and it drastically increased the prolactin level in my body. I've gained around 2 cupsizes, I used to be a C but now I'm a DD, and even higher depending on the store. I'm super upset about it. I thought having big boobs would be nice but I really don't like it that much and it's a huge insecurity. I mean, I like having big boobs but I'm a dancer and it's super hard to you know.. dance with big boobs I guess, it makes it hard because I can't even DREAM of wearing strapless bras, and I can't have any kind of strapless dresses or tops because I don't want anyone seeing my bra or bra straps. I know I'm 15, but if anyone has had breast reduction could you please give me some information? Obviously i'm not going to do it until i'm older, but I don't really know how it works or the cost or anything like that I guess.
