Thanks for the input. She did bring me back to the present, kind of. I don't think it really went how it was supposed to. I was told to pick an image to focus on, and then held pulsing things in my hands. The thing is, that image just got stronger and stronger and when she stopped to see how I was doing I was too overwhelmed to give an honest answer. I told her I couldn't leave the room without being able to calm down. And she led me through some meditation. But when I got into my car, I just sobbed. Last week I went back and told her it was too much. She said we could take it slower.
The problem is is that even with that reassurance, things have gotten WORSE. More triggers. More nightmares, etc.
I guess I'm just afraid that she'll take me too far without realizing it. I don't have a gauge of what is OK with this kind of therapy and what isn't. Nothing that I thought about (in that session) feels any less intense or less tied to my emotions.
