Breast reduction at 16?

Hey, so umm I'm sixteen year old and live in Europe.

My boobs already started growing when I was 9 years old and I currently have a G-cup. My neck and back often hurt and it's really difficult to find a bra that fits. I also have trouble finding shirts and dresses that fit me because of my bra size. I am extremely insecure and I hate my body because of my boobs.

I am not skinny but not overweight either so I'm trying to lose a bit of weight in the hopes that my boobs will become smaller too but I don't really think it's going to help.

I'm sorry if my English isn't that good btw. :/

So I guess I'm just wondering if anyone wanted to share their experiences with a breast reduction because I really want one. :(
