Time to Think (over think)

I made Sunday my rest day for several things, including doing any grading, etc. I know I need that day, but I realized yesterday that evenings and Sunday's are really hard for me because I have too much time to think. During the weekdays, I keep pretty busy working on grading and other projects but evenings and weekends just give me too much time to over think everything. I am not sure what the solution is, I just know it's a problem I'm having right now. I know part of it also comes from the fact that Tom spends most of his time in bed and so when I'm not busy, I just get really lonely. He has only felt like coming out once in the evening to watch TV with me over the last few weeks. So I guess I need to brainstorm some solutions for how to deal with that time so maybe I cope with it a little better. I know I need down time but I don't need overthinking time lol.
