My weighted blanket helps me a lot. So does aromatherapy type stuff, I have a Scentsy that I use to melt scented wax cubes in and there's so many amazing scents available.
When I can get the energy to do it exercise helps. Mostly taking long walks.
Videogames help my anxiety too. I also enjoy reading and that calms me down/grounds me a lot.

I have a worry stone I hold on to/rub when I'm anxious. It's just a small polished smooth stone I bought on Amazon. It's like a fidget type thing.

Meditation is good too, and yoga.
