Breastfeeding help please!


I wasn’t able to BF my daughter and always wanted to try with my second. I don’t know what’s wrong with me though. My boobs but especially my nipples are so sensitive that if my daughter,4, accidentally touches them it makes me really angry. But I don’t know why. It’s not just her. If I accidentally brush them on something it makes me see red. What the hell is going on and will I even be able to BF if I’m feeling like this?
