p.p depression

feel lost. feel like I can't do enough for my newborn. cry is the only thing that relieves the feeling of not being needed or good enough for this little one. I'm paranoid somethings going to go wrong. Idk. I'm really not liking myself and my boyfriend has her in another room and is not being supportive. 💔💔 I want her in my arms but she's going to cry. first day home and I feel bad for taking my 3 hour nap earlier. Idk?? help me.
