Some Ts are anti-label, and that's fine. And to ask about your intention in wanting to know a diagnosis is also fine. But the asking if you "want" to be a certain diagnosis I find weird and patronizing. It would be not useful to ask such questions of a friend who has no expertise with which to answer them; but to be asking a professional who should both be able to pose an answer and has an obligation to do so, seems reasonable to me. To pathologize such a request seems absurd.
