I like the sitting on the floor idea, too. I am in the same boat as you, in that as soon as I walk into therapy all of my emotions disappear and I just sit there smiling through the whole session as I talk about stuff. But not getting to the heart of anything. I think next week I am going to bring my journal, or a drawing or something that will get the conversation going on a deeper level. It's frustrating to have this fear of vulnerability!
