The same thing happens to me, and I'm sure it happens to most of us. I shut down a lot of the strong feelings that I feel when I get into T's office. I want to share with her how I'm feeling in the moment, and she wants me to do it too. I think it's due to a combination of factors: anxiety, distraction of being there, and not quite knowing how to access those feelings.

My T and I do meditation/breathing first. Sometimes that helps. Or we do art therapy or the methods she uses, IFS and EMDR, which help me access feelings. I know most Ts don't use those techniques, though.

I'd suggest talking with your T about this problem and seeing what she suggests.
