Overwhelmed and PP depression...

I've seriously cried more today than I have in a month. And it bothers me bc I know it upsets the baby. But my boobs are swollen like up to my collar bone and are rock hard. They're so heavy it's hard to breathe. My vagina hurts so bad, like nothing makes it stop. And we fed the baby about 5am and he refused to eat again until about 1230. So that freaked me out. And it's even worse when he's crying and I've checked everything I can think of, and nothing stops it. It's like scream crying. And there's nothing else I can do to make it stop. Idk if I'm just exhausted from getting up and not getting any good solid sleep, or my hormones are still messed up. My boyfriend trying to make me feel better and tell me I'm okay and baby is okay. Which I know he is. I just feel like I'm not doing as good as I thought I would. I'm tempted to just pump and bottle feed him breast milk but I don't want to lose the bond of breastfeeding. It's gotten to where when the baby cries, I cry. He's only 4 days old and I love him to death. But I think I'm not being a good enough mama because I can't comfort my baby..
