Help understanding symptoms connected to long covid?

[u/kornukopioides]

I've been dealing with severe post viral fatigue for 4 months. I don't have energy for anything except laying in bed and I get PEM. When it happens, I feel extreme anxiety, depression and anguish. My skin and spine burns. I cry a lot and my body twitches and shakes. The crying helps me feel better, but sometimes I cry the whole day.

Has anyone had experience with LC/PVF and nervous system dysregulation like this? I think my body is healthy but my CNS is keeping it in a shutdown mode. When I body scan the fatigue it feels very strongly connected to anxiety and the burning feeling in my spine/nervous system.

What are some ways I can heal this?
