We talked stuff that works you up, how about things that you do to calm down? What techniques, activities, mantras, stims, etc. do you do to keep yourself comfortable and safe? Feel free to share what you’d like - and something kinda cool is that you might end up helping someone else down the line.
Crypt of the Necrodancer on steam is a fantastic rhythm game, and you can use your own music on it. The switch version is portable, which is a plus, but there’s no ability to swap your music in.
I also second Theatrhythm! Final Fantasy music is almost universally gorgeous.
