Help.. so disgusted with the size of my boobs?

Im 17 and hardly even fill an a cup.. Which is disgusting. Im not over or under weight, i weigh about 140-145 and im around 5'7. I hate the amount of space in between them. Im so self conscious, that for the past 3 years or so, ive been wearing 2 bras because if i wear 1 it just looks gross. Ive thought of getting a breast augmentation at 22, and hopefully be able to save up money for that. And no, im not going to "get comfortable" with the way i look. If this has bothered me for 3-4 years now, thats not going to change. Is it the right idea to just go with surgery? I mean thats the only way to get them a decent size and shape, so why not..
