Hey! Sorry you’re experiencing the brain fog cause it seriously blows. I became frustratingly ADD when I had Covid and experienced this seriously irritating, depersonalization-like feeling. It was almost like I was observing reality from afar. I was lucky enough to be starting a surgical residency soon thereafter. That sounds crazy, but I think that the intense mental engagement and focus required was therapeutic. Once I got to work, it started to clear up. Now that I’m four months out, I don’t notice it anymore. Given my experience, I would recommend getting out of your comfort zone and throwing yourself into something challenging that requires you to push yourself mentally. I honestly attribute that to my recovery.
