I might have gotten off with not nearly as bad as I could've, but I still wish I had never gone through puberty physically. I never went through it mentally, and I didn't get the one thing I could've used more of, that being height. It was completely pointless. I wear very loose, form-hiding clothes, so I don't have to deal with annoyances like staring or anything.
So long as the surgery is less painful and inconvenient than keeping what you have, and you aren't disturbed too much by the whole medical thing, I'd say go ahead with it if you want to. Don't let anyone else make such decisions for you, though.
