Cats,
I hope you are feeling a little better this morning. That sounds like it was so difficult!
After I had a few nights like that and an emergency session with my T, he made a voice recording on my phone reassuring me that I was ok, and I've used it a few times since. I also make lists like what Stormy suggested and if I'm home I watch something comforting, like a Winnie the Pooh tape. I write it all down to help get it out.
Nothing I do really stops the flashbacks, but they do tend to fade in intensity after the memories have expressed themselves. Its almost like I have to go through them to let my brain finally deal with it. My T says it can be a good thing (even though its horrible at the same time) because it means that my brain is strong enough to finally handle it and that's when the healing can start.
How are you now? Have you heard back yet?
