Oh my gosh! That sounds like one of the most extreme cases I’ve heard about but I don’t know anyone personally with post covid symptoms other than fatigue and a little brain frog. I have heard a lot online though but this is pretty bad, sorry about that. Mine wasn’t that bad but after covid is when I noticed I actually needed help with my already diagnosed ADHD. Fatigue was huuuuuge for me too! So bad!! I was taking naps everyday for about a year (I never napped before) but that has been slowly getting better so I only need like two naps a week now. Adderall also helped me with the fatigue.
I hope you can get everything figured out over time! It’s good that you had some doctors take you seriously. My doctor acts like post covid symptoms don’t even exist
