Cardiomyopathy/virus/fetal growth

I could use some reassurance. A couple of months ago I went to my OB, who told me that I have a 20-40 percent mortality risk during labor due to cardiomyopathy and that I needed tertiary care, My EF ratio is 40-45. This just a couple weeks after the father abandoned me in the most cruel and shocking way btw, leaving me curled up shaking and crying for many days. Fast forward to now with all of this virus stuff and last I knew she was a little small (15th percentile), I’m older (38) and super stressed and exhausted... I just keep thinking that if I get this virus I won’t make it through and I don’t know what would happen to my baby. I definitely don’t think he would be a good caregiver, especially considering he suddenly didn’t claim her anymore when he rapidly discarded me. I know thinking this way is not going to help but I just feel convinced I’m going to get it and either die or be in critical condition and separated from her and now they are talking about many waves of it? I’m just going to lock us away for a year! 😩 someone please calm my nerves and tell me I’m being irrational? This pregnancy has been one heartbreak/stressful day after another, my gosh. Appointment with MFM specialist and cardiologist this week... and I’m scared to go too bc no one seems to wear masks around here
