I was feverish for a couple days last week and the entire time I just moved the goalposts - "this really sucks, I feel awful, and I'd love to just go back to the mundane ASAP please and thank you", kind of lost it one day in late July trying to get a tooth extracted with no insurance, but it did get sorted thankfully. Was very close to having to spend money I didn't have for an oral surgeon but narrowly found a way that wouldn't put my back against the wall financially on top of being frustrated with how health care left me in a position where it's preferred I go septic and die if I can't pay you money right now.
Basically how I deal with all physical health issues. I accept I can't exactly fix something in the moment and ride it out until I'm at my usual baseline. It's always a reminder of the positives you do have once you come out of it feeling normal.
