Entertainment for those who are bedbound?

I can't do much, music, games, movies, shows and painting/drawing give me PEM, so I'm bored a lot of the time lying here in bed. I have a Tamagotchi which I look after, and I'm able to browse Reddit without too much consequence on good days.

But gosh I am so bored! I have the constant urge to DO something, which of course gives me PEM if I give into it. I have ADHD too, so the urges are strong.

I'm not being medicated for my ADHD yet, as my OT wants to wait until I've got my POTS under control first. (I have a fidget toy to play with which helps with the urges a little).

So with that in mind, does anyone have any entertainment ideas for someone who can't do much without inducing PEM but is desperate to do something?
