I've had the same thing with caffeine causing significant anxiety that didn't occur beforehand. One of my medications also stopped working for a month afterwards. I'm surprised there's not more concern in broader society about the multi-systemic health issues this infection can cause before barreling into shoving people into crowded public spaces again, where they can catch it repeatedly.
it appears that other infections can cause similar if not identical problem, it's just that with COVID a tenth of the planet or so caught it in the span of a few months and it's (slightly) clearer what the effects are.
I feel we are shoving people into crowded public spaces because we currently have no practical alternative
