Severe anxiety

This past week has been very hard for me for whatever reason, I’m not sure what this anxiety is stemming from or why it came on so quickly and so badly. I’m 23 weeks, and I’ve been thinking a lot more about labor and delivery. I know I still have time but that’s not the point. Everything’s been so difficult during this pandemic and I’m starting to feel really alone. I do have a huge support group but not having my baby’s dad with me at appointments or ultrasounds is taking it’s toll, especially since this is our first child. I’ve been having nightmares and trouble sleeping most nights, I can’t seem to stop thinking about everything that could or might go wrong. I’m horrified of hospitals, needles, doctors in general. I know that’s all part of having a baby but with it not being a planned pregnancy I’m still learning how to cope. I feel like I’m starting to get a little depressed, I find myself alone most of the time, avoiding interaction with everyone. Does anyone have any advice or suggestions on how to cope with this anxiety? I do what I can to get out of the house, go for walks, spend time with my boyfriend, sit outside and read. But nothing seems to be helping, I almost feel lost in my thoughts.
