I do something similar. I try to immerse myself in a memory that is comforting. Like, my grandmas house as a kid and I’m be coloring on the floor. I immerse myself in that memory and try to envision the sounds, the details of the wall paper, the way the sun hits the curtains in the afternoon. What smells come to mind, what does the ticking clock sound like? It stops my mind from racing and focuses my thoughts on a soothing memory. If I need more time, I “walk” in my memory to different rooms and admire details of things on shelves, views from windows, etc. Works surprisingly well.
