Since it hasn't been mentioned yet, I had two debilitating flare ups of EBV (Epstein Barr Virus) post covid. It's commonly latent (apparently 90% of humans carry it) and will opportunistically flare up when the immune system is compromised. It commonly causes mono in teenagers, but more generally will cause crushing fatigue and related symptoms. There are no known cures, but plenty of things you can do to support the immune system. It can be detected with a blood test. If you think you have long covid, get an EBV test - might help.
