Advice on boob jobs

I've been reading about the possible issues and problems. Is it worth it? I've been wanting them for a while and I'm an A would like a full B. I don't want to get addicted to plastic surgery and I don't want any health complications. But I am so unhappy and honestly am starting to hate myself. I'm afraid of them breaking. Is it true after a few years you have to get them redone? I'm really active, could that hinder anything?

Can any of you ladies had gotten them give me your experience and how you feel about them now? If you have before and after pictures that would be cool (sorry if that's weird). And if you regret it/would do it again?
