I'm so sorry you're going through this. It's awful, I know. All I can think of to say is to try to remember that it's not happening now. Believe me, I know how hard that can be, especially when you're sort of reliving it all, but try to just keep repeating to yourself: I'm safe now. This isn't happening now. This is in the past. I'm okay now.

It can also help in the moment to practice getting a good image in your mind of a really safe, comfortable place that you can picture yourself in. For example, for me, that place is a beautiful pond, with trees and flowers all around. It's totally protected so that no one can intrude on me.
