Take care. I do validate and recognise exactly what OP mentioned, I suffered of it from the later half of 2020 all the way to the end of 2021, things are slowly getting better since December when I changed orgs (inside the same company).

I'm still far away from how I used to perform, I'm doing therapy and it's been one of the worst issues I've talked about for a while. It creeped into other areas of my life and now affects my day-to-day life and hobbies, the pandemic just made everything much worse.
