HI feb2020user. Welcome to Psych Central. I hear you that you need hobbies or something to focus on. When I have nothing going on I can start to jump on the "thought train" and that is never great.

Grounding helps me. Here is one series of active but not exhausting activities that has 8 segments so when you get tired of one you can try another. 5 minute Tai Chi Part 1

Hope you get the support you are looking for.
