Mine:
1 SleepPhones wireless headphones is definitely the best single thing I've got since getting sick. Listening to audiobooks has been one of my main activities but I'd end up with my earbud wires wrapped around my neck. These I can sleep on in any position very comfortably and pull them down over my eyes when it's too bright. Must have.

2 on that note, an Audible subscription is also really good. You can gift books individually or a couple months of subscription time.

3 This heating pad is the best one I've found after much experimentation. Heats up really fast to a good temperature and is very flat flexible so you can wrap it around aching muscles.

4 This massage stick is also very nice for especially achy muscles that are hard to get into. It's really helped me break up some of my worst spots.

5 My wife bought and hung this hammock for me so I could get outside a little. Cheap, works well, and lets me see the sky a little again.

6 A kombucha brew kit has been pretty fun for me, doesn't take much effort for a good payoff, and supports healthy gut bacteria. There's not much more to it than making tea and mixing it in jars with fruit. Plus a lot of waiting around, but we're doing that anyway...

7 Finally, and this one is weird as a gift but it's still helped me a lot, is a subscription to Freshly. Freshly is a weekly food delivery service like Blue Apron or Hello Fresh, but they send you complete ready to heat meals instead of ingredients to cook with. Very high quality fresh food. I think of it as heating up really good leftovers. Been super helpful for me as cooking and doing dishes became too difficulty.
