Uhh... Wow. If there's no other side to your story and this psychologist acted this way, then that is just... well, it's incompetent, frankly.

If they are actually using your good insight as the single deciding factor in your not having AS, then they are doing this absolutely the wrong way. Insight has nothing to do with diagnosis of AS, one way or the other. Plenty of people who have AS know they have it and know something is up even without a diagnosis. Plenty of them have gone from doctor to doctor trying to figure it out because many of these doctors aren't used to diagnosing a "childhood disorder" in adults.

There's no telling whether you actually have AS; you still don't have an answer, thanks to these doctors. You should probably go on the basis that you still don't know either way. That these doctors made such an obvious mistake tells me that they're not qualified to diagnose AS, because they don't know enough about it to know that it hasn't got anything to do with how much you know about yourself.
