Bra size and breast feeding

Tiffany
Okay well the first question is, I have been pumping four months and he has been strictly on breastmilk. It's summer and I am a teenager(16). I really need a job for me and him but I am not gonna be able to pump. On top of that, my boobs are so chapped and hurt. I really want to stop breastfeeding Bc it would be easier, but my goal was a year. So imma feel like a failure if I stop but I don't think I can do much more. Especially going on vacation, I won't be Able to pump but I'm also scared to stop lol. Advice?
Also, I was an 34A before I got pregnant I am now a 36C, I really need new bras and I got medium bondoos, I'm only getting a few bras. But will my boobs stay a C or go back to an A. I'm really hoping they won't. But what happened to yalls boobs lol?
