I hope you are able to get some rest tonight. Fatigue from the worry sucks!
I found physical exercise helpful. I started putting on my tennis shoes and power walking. I would walk around and around and around the neighborhood until I was sweating and exhausted. The madder I got, the longer and faster my stride got.
Usually by the time I got home and took off the tennis shoes, I was also removing the frustration. I was ready to focus on me again.
