Same here. At home I can feel much more and I have a lot of thoughts about difficult things. But then, with T in the room - there is nothing :-/
However, I have to say that it changed a little bit. At the beginning, I was completely disconnected from my feelings (when I felt something it was rather something physical - like weakness or tension).
Now, more often I *feel*, I'm connected to myself. But sometimes there are sessions when again I have no access and I don't know why.

I've noticed that it happens when something more difficult appears and my mind wants to cut off from this. Then usually I say that I feel nothing, I don't know what to say etc. and we talk about this (how does it feel to feel nothing). And this causes more trust between me and T, and at the next session it's usually better
