Ya know what? There is nothing pathetic about your being upset about it. It was not some little thing. It was a horrible and cruel thing to do to a poor little girl. I am so sorry it happened to you.

I agree with the people who said you should share your post with your T. Also... I believe a therapist might have led parents to do this. Many, even most therapists are good. But not all are. And lots of strange ideas have come and gone in different branches of therapy.

As far as a wooden char goes, even without having experienced what you did, I am having a hard time imagining being comfortable in a session while sitting in a wooden chair... add the emotional triggers, and forget it!
