Hi Robin Holly,
My symptoms have not been as severe or pervasive as your symptoms. My most prominent issue is brain fog. It definitely interferes with my daily functioning. I am not driving. I have a lot of trouble with basic household chores. I have lost sense of time, and have challenges with paying bills, banking and problem-solving. I live alone with no nearby family.

A therapist who works in a Covid clinic has recommended Speech Therapy for an eval and cognitive retraining. I don’t have a speech problem that I know of.

I have researched local neurologists, but I cannot identify one that I would use. (I am a retired health care professional and know several of the neurologist in my area.

My latest find, is a Neuropsychologist who specializes in evaluation and rehab. A family member used him in the past & I was very impressed. And…he accepts Medicare.

I am mentally clear for about 2 hours / day. During that time I have watched some You Tube videos about Covid brain fog. I stick with qualified professional who can make suggestions about resources in the internet. I have also added some brain stimulating activities into my daily life, easy Crossword Puzzles and Suduko (new to me)
I don’t know if any of those suggestions fit your situation. I wish you the best in your recovery. One coping mechanism that I have learned over the past decades is, “never give up hope.”
