'is my energy total shit and my head empty because of depression, because i haven't eaten enough, or have i contracted covid, or perhaps something else entirely' is a fun process of elimination
you get enough brain and body problems and then every time something's wrong you have to run down a long tedious checklist like you're clearing out a gacha daily
more i think about it with just how fucking tired and unable to think clearly i've been, it almost certainly is covid even if i have had zero cough, huh. asssssssssssssssssssss
