I think a lot of it has to do with people just not feeling well plus the stress of everything. I know when I went through my decade-long health situation, I had a lot of the same symptoms of systemic inflammation leading to muscle & joint aches (fibromyalgia flares were the absolute worst), chronic fatigue, brain fog, depression, etc that seem to also be at the heart of the vax melange. I know I would sometimes make rage posts here on FR that later I wished I could have deleted, and often I would go off on people for very minor mix-ups. I’m trying to be extra nice and patient with people now to make up for it.
