Postpartum anxiety

I think I have postpartum anxiety. At first I wasn’t sure if it was normal FTM worry. But I don’t think so. Anyone care to share their experience? What did postpartum anxiety look like for you? I’m not sure if this is something I can just deal with or if I should seek help. I think I try to convince myself it’s not that bad. I would say I’m coping okay tho. I’m able to enjoy my baby but I have a constant fear she’s going to die when she’s sleeping or not in my arms. I wake up in a panic multiple times while she’s sleep to make sure she’s alive. I check on her every few minutes to make sure she’s breathing if she is sleeping somewhere besides my arms. I’m just so scared all the time. I feel very nervous leaving the house and going into public. I’ve never had anxiety before so I’m not sure how “normal” this is as a new mom. Btw I’m 8 weeks pp.
