Breastfeeding

I want to breast feed baby #2 but I'm sorta debating with myself. I know the benefits but I felt like such a failure with my first when I couldn't continue past 6 months of pumping and couldn't ever get him to latch. Also my boobs already hurt so bad this early in pregnancy, idk if I'll be able to handle to pain of the milk. Any advice? Tips? Personal opinions?  Hopefully no bashing 👍🏻
