Help! Self conscious!

I'm 16 years old and before I got pregnant my boobs were huge. I hate it. I see all these girls with small boobs and mine are literally the size of cantaloupes. I'm not kidding!!! I can't wear any of my old bathing suits. I have disgusting stretch marks on them too. I feel so self conscious. And my left is bigger than my right. I feel so ugly. Anyone else going through this???
