snappydad,

1st, It sounds like you have tried to push through and continue to live your active life by tricking your brain, etc.

You don't mention anything about your quality of sleep....

What meds are you on now and what meds were you taking when this started?

Have you had Covid or received the Covid vaccines and boosters. When?
There are some who experience some extreme neuro complications from a Covid infection and from the vaccines/boosters. It is called Covid brain, like chemo brain.

Years ago, we had a man here on NT who had a horrible and lasting struggle after a marathon of gaming.

You sound tightly wound. Maybe a perfectionist. Maybe with a "Find what is wrong and just fix it" attitude. With PCS symptoms, often we must surrender to how our brain is working, give it a rest, then slowly start returning to past activities.

You mentioned a psychiatrist and depression and anxiety. Do you have a history of struggling in these areas? Hard driving perfectionists often do. They often self-medicate with activity.

Do you consume energy drinks, Red Bull, 24 Hour, Monster, etc? even just coffee or other sources of caffeine? What about alcohol or other recreational substances?

A stressed brain can become very sensitive to many things that were never a problem before. You might benefit from an elimination diet and start carefully consuming only foods and supplements that are known to be low inflammation, low allergic, with minimal sugars/carbs and high protein and fats. No soy, at all.
