Postpartum depression

I’m 4 weeks postpartum and I have had really bad depression lately. I have so much anxiety from worrying about my child’s safety and generally anything bad that could possibly ever happen to my baby. I’ve been very fixated on it and especially with Covid going around I really don’t want anyone but my baby’s dad holding her. I have so much pressure from family to see her but I still haven’t gotten to some family members yet. The times that my baby has met other family members I’ve had extreme anxiety and I get so anxious to get her back when someone else is holding her. Anytime I’ve seen family with masks of course it just feels like torture. With covid as an excuse to stay away from people I’m just worried it’s making my depression worse. Does anyone have any tips for me ?
