I try less stressful versions of my former activities. Like i used to play competitive Scrabble at a club in person and it was very intense, i lived for my rating and ranking. Now i just play at home on my phone against an AI with the level set very low so i win every game.
I also developed new low-stress interests, like poking around the Internet for jokes. Laughter is the best medicine. I also like watching favorite shows and movies and comedy specials over and over. I really like musical comedian Bo Burnham's "INSIDE" on Netflix. He's got some stuff on YouTube too. "Welcome to the Internet" is from "INSIDE." I don't feel well enough for new material but i have a high tolerance for repetition of old favorites. Favorite novels too.
Spending time in nature helps too. Trying to be mindful of the wide open sky, the giant trees, the ruffling bushes, the pretty flowers, the refreshing breeze -- it's very rejuvenating.
Hope this helps!
