I felt traumatized by the session week before last, when I went into session in a trauma state (drama with abuser right before session) and then the activity happening around the therapy room caused me to go into flashback mode. A child alter sat there frozen completely disconnected from t (T tried to connect and reach us but couldn't) experiencing past trauma where
Unfortunately we stayed in that traumatized state for most of the session and left in it too.

I emailed the t several days later explaining what was going on internally at the time and gave suggestions for what we can both do to help prevent it from happening again. We tried some of those suggestions in this weeks session and it went much better. We will keep talking about strategies to use to help ground us and keep us in the present when flashbacks occur.
So I wouldn't say my T traumatized me, but the therapy experience was traumatizing. My T is really good about working with me to find things that help though. She recognized we were not present but none of the strategies she was using helped and she was really open to trying new ones.
If she wasn't open to trying new ones or blamed me for what happened and how I was in any way at all I would have experienced that as T traumatizing me. But she didn't and wouldn't do that.
