Sometimes I like to take a finger and run it along the sides of my other hand's fingers, slowly breathing in while you go up and out while you go down. Your fingers are very receptive to sensation so it feels kinda funny, but it helps me ground if I do it slow enough, and timing my breathing to the movement helps me focus. To everyone else it kind of just looks like a fidget.

If you keep a little bottle of peppermint oil and a small cloth or diffuser necklace that might help since the smell is cold and intense. That’s what I usually do
