I have been having the same issues. I have told T of my discomfort with the fact that I have known her for over a year. She says that I am doing better. I have not seen her for a month and haven't missed her much. I used to cry if I couldn't see her and then lose my focus. I keep wondering if I might make my appointments once every three weeks instead of once every other week like when I started with T. However, I haven't mentioned it to T but I suspect she would not be opposed since she keeps bringing up the cost of co-pays and saying that I am doing better. She even said that she told previous T that I am doing better. I think she is pushing a bit for a closure soon too. If you are thinking about leaving, I would talk with T and look to see if your goals have been completed. How long do you go in between appointments and how does that effect you? I remember a time when a month without T made my focus real bad. Now, I seem to have normal focus even after a month without T. However, I still don't have the crying in control which is why I think I still need her for now.
As for self-disclosure, I am sharing more and more with her. I just seem to be doing more of the work by journalling rather than talking to her about it all. Is that the case with you?
