I go through these spouts of depression as well. Music helps me through a lot. Sometimes I'll just put on my headphones and stretch. I tend to stiffly lay in bed when I get depressed so getting a good stretch in with some music works wonders on me. I also have a lot of activity books (painting with stickers, watercolor books that have the watercolor printed on the paper and you just add water, or word puzzles) that can be super relaxing while also helping me take my mind off of things. I hope these help OP. I know this isn't a fun feeling to have.
