Oh, Button, are you talking about something that occurred in class, not in your own personal T session?

I think you are, re-reading your original note. But I would echo hankster's point-- I would think it is part of your education and part of the job of your teachers to self disclose. If you can't handle your teacher disclosing, how are you going to react to clients' disclosures? I don't think that any of the "rules" that apply to your own personal therapy can be applicable to what you are supposed to be doing in your training for T school.
