Please help my breasts are ugly guys opinion also?? :'(?

Ok well im about a b or a c but no bra fits me. I have had depression for a while and my weight bounces around like crazy. I lost about 20 pounds in like a month and it mostly dissapeared from my breasts. I have about an inch or a little less than an inch of excess skin. My areolas are different sizes and one of my breasts have more excess skin than the other. I am 15 and ik i might still be growing but i need a way to get rid of this skin. I have a really big ribcage so when i lay down it pushes my breasts towards my neck and they look hidious the areolas are just too big. When my breasts are erect they dont look as hidious but tey still r. Please dont say love urself or boys dont care they just want breasts cause thats not true. Ik my boufriend wont care but i want to fix this for me. Ik chest exercises might help but how long would it take to get away maybe a half an inch of skin? If i do pushups and lift weights and chest flies every day for a long time how long will it take? I also have some stretch marks what can help get rid of those? Thanks "/ and for the guys how much would this bother u? Would u dump a girl cause of this reason please b honest and no joking around
