Breastfeeding the 2nd time

My LO is only a few days old so I feel so super shitty for feeling this way. I had such a hard time with my first. I couldnt get her to latch and ended up pumping, but that gave me such bad anxiety that I quit at 3 weeks.

I'm trying to breastfeed again and so far it is going better BUT my nipples hurt so much, I just want to cry and cry. All the nurses and lactation consultants say her latch is fine.. she wants to be on the boob constantly. I gave her some formula because she wasnt peeing and I felt relived to have her get milk..

I have 21 month old and I can't help but think it would just be easier to bottle feed. I'm already starting to feel anxious again about the whole process. I'm so anxious to breastfeed when I'm home alone with my toddler and newborn. I know how to bottle feed.. I hate this pain so much. Everyone knows I'm trying and I feel like I'll be so judged for quitting so early on but I just want to give up.

Am I terrible for wanting to give up so soon?
