Different breast sizes, I need advice.

I am 15 nearly 16 and I have two very different sized breasts.

My right one is a lot larger than my left one (a size and a half difference nearly) and I know I am still maturing (I hope) but I am so self conscious about it, Im already severely self conscious of my body and myself and this makes it worse.

Bra shopping is a nightmare and I’m so uncomfortable all the time.

My body is just so ugly and I want to change that so that I feel more confident and I’m trying to work out and become healthier but I have next to no motivation.

Any advice or eve wisdom you can give me?

Should I see my GP about my breasts?
