It could be chronic fatigue syndrome .have u talked to your doc about your symptoms?

Yes that is a good description of ME…

Idk .... As somebody diagnosed with M.E., I think being able to dance for that long doesn't sound like M.E. to me. But this is not a diagnosis you can make yourself. See a doc. If it is M.E., waiting and pushing yourself can do some real damage. I wish I had not pushed myself for years before acknowledging I needed to stop.
