Hi Philonoe
I find trying to get back home into my safe space helps. Some days I want to listen to music- just as background music. Other days I crave quiet and don't want to listen to music at all. Doing hobbies- whatever interests me at the time helps- something I can get lost in and try to shut out outside thoughts.
Sometimes venting my day can help- either to someone in person if there's someone about, or through communicating here on the forum, or just writing things down, so it's not going over and over so much.
Often after a day at work, I'll come home, have dinner in front of the TV, and watch something that either doesn't require too much thought or maybe put a movie on- something I can tune out to. I create myself a little nest on the sofa and settle in for a bit.
When I'm really wound up or overwhelmed I find jigsaw puzzles really helpful- they require enough concentration that worrying can't take up all of my energy and focus if I'm trying to work on one. I'm getting myself a bit of a collection of 1000 piece puzzles.
Allowing myself "recovery" time after a day with a lot of interaction seems to help me reset though. That might sometimes mean that the day after work is sometimes a total write-off in terms of getting anything done around the house, but if I'm not feeling comfortable, I'm not going to achieve anything anyway.
If the idea of some kind of ritual, or a walk works for you, go with that. What works for each person is going to be a bit different.
