I feel for you. I experienced the same thing for about the last decade. It turns out meds I was one were not working for me, but against me and put my brain chemistry out of balance.
Fortunately, I found a doctor who made changes to my meds. I think I know how Rip Van Winkle felt when he finally woke up.
it woudl be awesome to wake up with a boatload of energy, and all day long stamina- but it’s not in the will of God i guess- as i have tried and tried to fidn the cause- lots of medical workups tryign to find out what is causign it-
