Breast feeding?

Brittany • First time mommy❤️ I work in a body shop, my boyfriend has a 7 year old who I love as if he was my own.
Ok I have heard that breast feeding is extremely painful, I have read some women's nipples bleed and the baby ends up spitting up and it having blood in it because of her nipples bleeding, I have read where one women cried and had to squeeze her husbands hand just to get through the pain and honestly it's terrifying me! Please tell me it's not as horrific as they made it out to be?!?! I really want to breastfeed when my baby comes but reading those things kinda makes me want to run from it.
