My therapist urged me to think along these lines when we ended. I certainly tried. But the truth was that the ending blew everything else that happened into outer space. Becoming dependent and then stopping abruptly is no small thing. If the ending leaves the client in acute distress or feeling worse than before, I don't think you can consider that a success. It violates first do no harm. We live in a culture where everyone is supposed to put a happy face on everything, rather than being honest and real. Especially in therapy. If something causes suffering, it's ok to just say so.
