When I was suffering from symptoms I would:
- Listen to Podcasts
- Solve Jigsaw Puzzles
- Draw
- Re-arrange Items in House
- Do small renovations (drywall patching, paint chipped areas, fill cracks, etc)
You don't realize how limitless the possibilities are for hobbies until a few of yours are taken away. In my case I was always doing hot yoga, playing hockey, biking, playing videogames, or watching television. For a while I couldn't do any of those and had to improvise. I'm sure you'll find something you enjoy, and possibly even something that sticks with you after you're done.
I still listen to my favourite podcasts on a weekly basis, and I've ordered another jigsaw puzzle since getting better.
Best of luck!
