I accidentally found a new way to ground myself. My daughter bought me some hand cream months ago and I hadn't even opened it. A few days ago I used it and just loved the smell and the texture and I put it in my night time basket that I keep in the bathroom to ground myself.
That night I was upset and sat on the floor in the bathroom. I opened the hand cream and massaged it into my hands. I gently massaged each finger and slowly my breathing calmed down and I was able to ground myself.
I don't think it will help every night but it is something else I can try.
