Activities that require little energy?

I’m going chemotherapy right now and I’m very sick, tired and weak. I physically can’t do much but struggling to keep my mind busy. I’ve been watching a lot of tik tok, listening to music, talking to friends on phone, and working on my photography. However I can only do so much of that before getting bored. I can’t focus on movies but looking for ideas for things to do that requires little energy. Thx
