Stress in 3rd trimester

I’m 30 weeks and feeling a ton of stress and anxiety right now. This is my first after trying for over a year, going through fertility tests, and having a miscarriage. My hospital has just banned support persons from my state which means my husband can’t be there. June is a little ways out but the anxiety is killing me. I haven’t slept in two nights and feel like literal death. I bawled my eyes out this morning because I’m emotional and also overly tired which makes it worse. I’m considering changing practices and hospitals to a different on this late in my pregnancy. It just feels like it’s all getting upended right now and I’m worried the stress will affect the baby. I’m trying to keep calm but it only lasts a few hours and then I’m freaking out again. I just needed to vent.
