I don't know that that is possible. I mean, I've left therapists without giving them any reason or justification why, but I hadn't seen them very long so I doubt they felt at all "abandoned."

I think maybe if I, theoretically, was seeing a therapist long-term and just kind of disappeared off the face of the earth and they didn't know what happened, they might be concerned and wonder about me, but I suspect they wouldn't feel "abandoned," just concerned and move on. I doubt that it is all that unusual for clients to just sort of stop going, even long-term clients.
