Hang in there! I know exactly how you feel. The fog in my brain distresses me big time.
At this point I'm welcoming every opportunity I have to stay at home. I'm doing my best to not go anywhere or do anything. I did start trying to eat a salad every day and I've gotten a handle on the insatiable hunger for sweets I developed for a while there. I start my day with an exercise routine.
I still have brain fog and I'm an emotional mess, I'm starting to realize when my emotions slip now and at least I can tell myself it's just my brain misfiring and take deep breaths.
All I can do is wait for time to pass. I haven't counted days in a while but it's somewhere around 4.5 months for me now. Hang in there, 67 days is a long time I had trouble around that mark a couple times .
