Breastfeeding and Big boobs?!

So I want to breastfeed but I already have really big boobs I'm not talking about just some DD's. I wear a DDD but I'm pretty sure I'm bigger then that but anyway I'm just curious if there's any women out there in my situation that has breastfeed and it never been a problem. Idk I just feel like I'd suffocate the baby. 😭 HELP. Share your story.
