Do you mean your T deliberately scheduled two clients for the same time slot? If so, I think that is unacceptable. It's like she was counting on one of them not to show up. Or was the doublebooking accidental? If so, well that is not a great way to start, but these mistakes do happen on occasion. I have been seeing my T for over 3 years and I think there have been 3-4 times when two clients showed up at the same time for an appointment. A couple of times it was one of the client's fault. A couple of times it was T's fault.

Solarwind, if this new T made a mistake and double-booked, why do you think there is something wrong with you? If this T misrepresented herself on the phone to you, why do you think there is something wrong with you? Do you think this could be a communication issue rather than something being wrong with either one of you?

If there are thousands of Ts available, then there are probably a lot of them who will be a good match and can help you.
