I do have what I regard as mental or psychological disorders. More than one manifesting in my lifetime so far, I've had at least: eating disorder, anxiety, substance addiction, depression, mild OCD. I still can't see the "treatment" aspect in therapy. Yes, there is the condition requiring change and improvement, and I would love treatment that resolves it. I am a mental health researcher myself, and a pretty open-minded person, also I regard myself as quite self-aware. Still have issues seeing how psychotherapy is a treatment, so could those who see it in that way, explain? I am not trying to be sarcastic, just would like to understand. For me, psychotherapy is primarily structured social interaction (sometimes harmonious pleasant relationship, often conflict and, in a good case, conflict resolution and, pretty much a mix like most social interactions). It is "treatment" in the above sense:

treat·ment
ˈtrētmənt/
noun: treatment
the manner in which someone behaves toward or deals with someone or something.

But other ways? Maybe advice. Perhaps the advice part I can see as goal-directed treatment, but then I read all the time that therapy clients don't want advice and therapists are not supposed to give it anyway. So, what is it, really, as treatment? Especially the totally open-ended therapies that do not even claim to have an outcome in sight, just come and talk?
