From your description of yourself it sounds very much like you could be on the autistic spectrum since you havr trouble communicating yoyr thlughts & dont want to call them to find out WHY they are sending you there. You would rather guess incorrectly thsn just find out the real reason by calling them (my ex did the same thing & he is on the spectrum)

Our pdoc wasnt able to dx ASD for some reason & they like to send people to a specialist yo get that dx because it is complex to define correctly for a dx. They pribably suspect you are on the spectrum from your behaviors & interreactions so it is wise for them to srnd you there to get an accurate assessment.

Why they didnt talk to you about it, only they can tell you that answer. I know communicating & getting through informstion to my ex even though he had been a computer engineer was next to impossible & he would look at me as if I were speaking in a foreign language. It got so I would judt tell him to do what he needed to do because it was useless to do anything more.. the harder it is for an outsider to communicate with someone the less thry communicate. Who knows if that is their reasoning or not. Maybe they asdumed they told you they suspect Autism or msybe they told you at another time & you didnt grasp what you were being told. There coukd be lits of reasons & unless you are willing to ask you will never know.

I would recommend folliwing through with their suggestion as you might get help you really need.
