Update: Been ill. Not dying, but it's not awesome; tried to ignore it but I have an autoimmune condition and some combination of stress, overworking myself, and that bout with Covid last month triggered it.
Please don't worry about me; but I can't say when I'll be fine again - sometimes I can just power through it and my immune system corrects itself. Sometimes, like this time, it just gets worse until I feel like my insides are made of acid and it hurts enough that I can't concentrate. Sorry.
