Normal or???

I just had my daughter 6 days ago, overall I feel better than I did while pregnant I struggled really bad with anxiety and depression the entire time. I wouldn’t leave the house, didn’t talk to anyone and my boyfriend and I argued a lot because I closed myself off from everyone including him. The first couple days after her birth were great but now I feel so suffocated by anxiety. I can’t stand not holding her or being in the same room as her, my boyfriend will hold her and 5 minutes later I’m sweating and jittery because she’s not with me. I can’t sleep at night because I’m constantly checking to see if she’s breathing, I don’t sleep hardly at all. I don’t even want to think about returning to work because the thought of that literally feels like a knife to the chest. What do I do? Is this normal? Do I need to talk to my doctor??
