I agree with above posters and you should discuss it with T.

I dissociated through most of my childhood, teens and twenties, which were very traumatic. Now in my late 40s, I'm trying very hard to cope with reality, which includes the reality of my traumas. Often in TT, I have a few moments where I know I'm going to split off, and the last 2 session I verbalized when I was feeling it. It feels AWFUL and is terrifying and I fear losing control but I'm trusting my Ts & Pdoc that this is the path to wholeness, integration and health.

Just reread this. I don't sound encouraging. I sound like misery loves company. I'm sorry.
