ROFL I do the 'I don't know ' thing with my T too!
She says back, 'I think you DO know!!!'
Arrrgh.
I usu blank out at that point.
A little while back I tried to say something, and my T pushed some, and I'm not even sure what it was about anymore, but I got SO angry and had to leave. Angry at myself, I kept saying somethin like, 'your not allowed to talk' or some such thing, I was furious with myself somehow I guess.
I am no spring chicken, I have some doubts that I will ever get past my barriers and be free

Anyhow, I wish you best of luck.
