@porcelainrose You have a lot of good suggestions here, and kudos for taking the step to talk to your doctor.
Some things that worked for me in a very similar situation :
-scheduling walks with friends or walks solo to listen to audiobooks, relax and get fresh air while allowing my body to recover
-hatha + yin yoga to learn how to focus on my breath and calm my nervous system (I hate meditation and need to be doing something with my body to calm my mind).
-a hot bath with dim lighting and no reading or electronics, just music or quiet
-reading books for fun: I like biographies, you might like fiction, scifi, history, something else. I crawl into bed with a cup of tea and a book, no electronics, and read a book
-volunteering in a field you care about: retirement home, animal shelter, environmental clean-up, soup kitchen? My weekly volunteer shift is one of the most relaxing things I have in my life. I check out from everything else, feel gratitude for my own life, and get a chance to really give back.
-improve your sleep hygiene, keep a routine, and really be militant about getting enough sleep.
-CBD (if legal where you live)
