I got infected with COVID twice, thankfully only after being vaccinated and didn't experience heavy physical effects but the cognitive issues I had on my first infection triggered a really bad anxiety. At some point I was playing chess with my girlfriend after 4-5 days from getting symptoms, after 3 moves (so pretty much still in the beginning of the openings) my brain simply could not understand what I was trying to do, like I couldn't connect a previous thought to the next, there was an impassable barrier between these thoughts that I couldn't get through. It got worse when I realised I had no idea what I was doing and while looking at the board I couldn't remember how the pieces moved, I looked at my bishop on the board and couldn't think where it could go. I started to cry, my whole job is to think things through, connect diverging thoughts, I got extremely scared I was going to lose this basic ability that enables me to do my job... I lost the senses of smell and taste for about 10 days so definitely had neurological issues from COVID, the feeling of not being able to think properly was the worse of the feelings. The fever was ok, never broke too high and it was short-lived for about a couple of hours, feeling my heart was not comfortable but bearable and I wouldn't get too tired. I'm so glad it was temporary, and so sorry for your wife having this lingering on her, I do not wish it to anyone.
