I feel the same. I think if T would be more open I could be more connected. Because now I feel that I don't know her at all

(I'm in therapy for 1.5 year, twice a week). And it's difficult for me to be open when this relationship is sooo one-sided.
During my last session, T. said (surprisingly) that she feels useless and generally she said more what does she feel when I'm not open and don't talk too much about myself. And it was amazing! Of course, I felt bad that she feels useless because of my problems with talking

but immediately when I've heard this I felt more connected to her. She was a real person with feelings.
After that, I think that for me it gives a lot when T share something about themselves (even if it's not something personal but just feeling related to our relationship or something like that).
