Although I hire my therapist to help me with certain things and, of course, to be present during my hour, I am not a lump of clay waiting for her to make me into something or make me feel good/loved/valued. It's not all on her. What I do with the hour is also of value.

So in your case, while your therapist screwed up, what did you do with that session? And by that I mean, not while you were in the room but afterward, now even? It's all material, if you want to use it. Because even if each one of us had a therapist check out during a session, we would have different responses, different issues emerge as a result. And that's of value, for those who use therapy to gain insight into their interactions, feelings, and behavior--and I realize that not everyone uses therapy in that way. If you're fine with yourself, and are just paying someone to hang on every word you say, then yeah...get your money back for that session. But if any of this is giving you insight into yourself, then maybe there was some worth in the session. It doesn't always have to be of benefit during the time in the therapy room. There is stuff of value to mine afterward. At least, that's how I approach my therapy.
