Breastfeeding tips?

I’m a g cup. Yes one up from triple d and I just find it impossible to feed in public. With my 10 lb baby and my what feels like 10 lb each breast and managing to continue doing what I’m doing.. like my poor daughter can’t breathe if I just let my entire boob flop on her face, and if I’m holding her and trying to hold onto my boob then I’d rather not feed in public as it defeats the on the go purpose. And I’ve had anxiety issues so just popping out my entire boob and sticking it to anyone who looks at me funny isn’t going to happen. I thought I could because it’s seriously natural and I shouldn’t care, but when your areola is larger than your baby’s head, it makes me super uncomfortable. I’m super modest and don’t even show a little cleavage in my shirt. Ps.. please no comments on JUST DO IT YOUR BABY NEEDS TO BE FED because I pump and bring bottles I’d never starve her, I’m just looking for tips for LARGE BREASTED woman. I’ve been with my aunt who’s a c cup and she can pop everything out and u can’t even tell it looks like she’s just cradle holding her son.
