They do not have to be able to figure it out for themselves, they simply have to be willing to try again with another therapist, who can help them look at what happened. If they no longer trust therapists, that is understandable, but limiting, just like it would be limiting to say, stop seeing doctors because one doctor botched a procedure. There are no guarantees because humans are fallible.

My posts were mostly intended to be about cases where the T terminates the client because they do not think they can continue to provide services to the client. But if the termination was malicious, that would be all the more reason that ending that therapy was in the client's best interest.

Therapy does not always have an ideal outcome, but that is not because it is therapy, it's because it is a human relationship, which simply cannot always have an ideal outcome. It also is not perfect, and hopefully is always improving, but making the best of imperfect circumstances is life as well.
