I'd say we just gotta be careful with "Chronic Fatigue Syndrome" (like you seem to indicate as well), which is like the name says a syndrome. So basically nobody can find out why and your illness gets subsumed under a "syndrome" that is based on the symptoms you're showing.

This makes it really prone to have different actual causes subsumed under this. I'm pretty sure I could've been diagnosed with this if I had continued talking to doctors, being sent from one specialist to the next. In the end I figured out what caused my fatigue myself and I'm feeling better than ever. This was way pre-Covid btw.

Can you share your methods for finding out what caused your fatigue and optionally what you found out for yourself?
