In the same boat, and I wanted to add the worst thing... your energy level (or lack thereof)

I used to be able to play games or work for hours (even without taking breaks)

Currently I can do some simple things like making breakfast, taking care of personal hygiene, or write this small comment without getting tired, but if things get a little bit more complex I am getting so exhausted that I need to go to bed for a while.

Take good care of yourselves people, having a brain quit on you most of the time really is not that great :(
