Ah, it reminds me bad times. I'm sorry you are in this situation right now. Very stressing..
If you feel like reading (comics or others), but you feel it does not help you to rest, one thing I would suggest is reading old favorites (if re-reading is not irritating to you).
I do that often. Because it's already known material, it does not take too much energy. And it can be comforting.
I also use music, as Rodimus suggested, although finding the right kind (not tiring you, not making you sleep, etc) may be a challenge.
If you are able to draw without making it serious, that's good too. No comic work, just doodles.
Any non-intellectual work if it's not tiring physically. Like reorganizing/classifying stuff unrelated to your work (like books, clothes etc).
All the best to you!
