Just an update. My experiments with "pushing myself" in exercise didn't seem to do much to speed along my recovery. Although I didn't have any symptoms while I was working out (in this case, jogging for 25 minutes at a time), later that evening, and the next day, I experienced worsening brain fog and depression.

I'm starting to realize that this is just going to take a while. In the hundreds of hours I've spent researching online, I still haven't found anyone who has discovered anything to speed up the process of recovery. It just takes time. I guess this will be an opportunity to grow in patience, which has never been a strong quality of mine.
