My daughter is a long hauler, and has found medication (she has tried several - it took time to get right) and mindfulness practices she got from her post-Covid treatment help her through. She has also learned to keep her hands busy (she crochets) and her mind occupied (books on tape or favorite movies/music.) She has good days and bad, but the good are gradually outnumbering the bad.

I hope this helps you.

PS And she is learning to pace herself better. Thursday, she felt invincible, did way to much, and is paying the price this weekend.
