Some people might disagree with me but I don't think you have to explain ANYTHING to her. You had one session with her. You didn't like her. That's perfectly okay! I've interviewed many many therapists and usually knew within the first twenty minutes whether or not I was going to return. With some, I didn't realize it until I went to three or four sessions. Once I decided the therapist wasn't someone I wanted to work with, I simply called and cancelled the session or in some cases, when they were fine with email, I would cancel through email and say that I'd decided not to continue with therapy--of course, I rarely said, "I decided not to continue with therapy with you."

Personally, I don't think I need to use my precious money for a session to tell someone that things weren't working out or didn't find them helpful. Much too expensive! Life is short and I figure that kind of session is a waste of my valuable time, and it is also a waste of their time too because he/she can spend that session booking someone else so they can hopefully find a long term client. I often feel that the whole "proper termination" protocol is ridiculous! Of course, if you feel obligated to go in and tell her she isn't a good match for you, then make the appointment and go in and tell her. Trust me, she isn't going to hear anything she hasn't heard before. Clients quit therapy OFTEN! Good luck with whatever you decide and even more importantly, good luck finding the right therapist for you.
