I don't think that a personal disclosure from my T that left me feeling distant from her would necessarily be an indicator of me needing to work on something. For example, if in an effort to find marked differences in our values, she revealed deeply racist, homophobic, sexist attitudes, my loss of confidence in her ability as a T, and my feelings of distance, would be based on something she needed to work on, not me.

I actually stated a number of concerns in my opening post, one of them being a risk of professional boundaries being crossed. One way in which professional boundaries might be crossed would be a T expressing to their client that she feels personally negative about them. It would seem to contravene ethical standards.
