I know one of the things that makes switching worse is the lack of sleep. Can you just sit quietly with your eyes closed like in a chair?? or maybe sit outside like that. Not go to sleep but just sit? Sounds like a lot of anxiety right now. It's that circle of things. You get it calmed down and then it just goes out of control.

Have you all been able to describe the nightmares to T and talk about it any? Sometimes that helps mine to go away.
