Surgery with Anxiety

This is something I don't even talk to my boyfriend or anyone i'm close to about. I'm hoping to get positive feed backs and advice. So, I'm really considering getting breast implants. The only thing that i'm worried about is that something could go wrong during the surgery and the aftermath. I already have enough chest pains with the anxiety (palpitations, stabbing pain, numbness, etc). I'm thinking of getting implants for an obvious reason like, my confidence. I'm 26 yrs old with a AAA. My body just didn't get the memo that they're supposed to grow by this age. Even after having a child, you would think they would get bigger. Most wouldn't think I have any confidence issue, but I do and it adds to my depression. I can't just wear a bra or bikini without padding. It's something I really want to do. I'm just afraid of the pain and worry about becoming more depressed in the end.
