Context: I’m autistic and also an aspiring therapist, and also a pretty serious Buddhist.
I think the biggest tension in therapy for most people is that even with the best possible therapist, the only thing that can happen in therapy that will make things better is for the client to change. Therapists know this, of course, and frequently have opinions about what changes the client “should” be making, and in the case of neurotypical therapists and autistic clients, those opinions are frequently wrong.
But I think also that autistic people typically have a history of people being wrong about what changes we “need” to make (because they don’t understand what things are easy or hard to change) so it’s easy to fake ourselves out and convince ourselves that no changes are possible, or desirable. And that process of faking ourselves out often takes place through intellectualization, because we tend to be good at that. So that’s something to keep in mind as a possibility.
(I tend to be sympathetic to the point of view of Narrative Therapy, which is strongly rooted in a postmodern critique of the medical establishment: clients are the experts on their own experience, and the role of the narrative therapist is to facilitate the client’s creativity and expertise in solving their own problems.)
