Covid.

I had covid in March 2023 followed by ~8 months of long covid. For me, the LC mostly hit my cardiovascular system and PEM (post exertional malaise). I exercised in small bits followed by naps. It is tough with long illnesses to find people that care. The isolation makes the LC feel worse. You can try searching "long covid support groups near me" because it helps to talk with others who know what you are going through.
Thirty one years ago (I'm 70) I had a moderate traumatic brain injury (extreme brain fog) so know how emotionally and physically draining it is. I exercised my brain in bits with rest between, such as puzzles, games, hobbies, any escape that feels good. Try to find something to look forward to each day, no matter how small, to help break through the heavy weight of covid. You are in a difficult place, and the healing is hard.

Thank you for your description of the successful use of “Pacing” while exercising your body (currently) and your brain (previously) to rebuild capacity.

I have Post-Exertional Malaise (PEM) and apply Pacing to all my activities throughout the day.

People can learn more about Pacing strategies online by searching with the term “Pacing.”
