I wanted to read and couldn’t. I picked up three different books today, read a few pages, and then tossed them aside grumble-y. I can’t concentrate when I’m worried. And I’m worried.
So I ran some errands, exercised, and then picked up my original book and … yup, put it aside.
I hate it when I want to read and can’t. What do you do when this happens to you? The mind a scattering of nothing and everything? The words just words?

My self care is cooking and crocheting. Sometimes when I can’t concentrate on words, doing something with my hands helps with the worry.
Working with hands is good, especially since you can only exercise for so long.
