I consider that out of about 6 therapists, I've had two successful terminations. One was driven by moving across the country (me) and the other one was a wise old therapist who knew exactly how to let clients leave with them feeling they had accomplished amazing things. I compared notes with one of his other clients, and we were both like, Hey, We Rock! We grew so much during the time in his office. Therapy was tough, but it was like Graduate School of Life, and we left with High Honors!
Very few Ts handle terminations in the proper way, IMO. And a lot of the time, it's driven by their own crap.
