Sorry to read you have experienced that reaction. I am in the process of diagnosis as an adult but believe that high school life would have been far worse if it was common knowledge i was different. As it stands now only one person in my life knows I'm even looking into it. Haven't shared it with my parents or family.
I think people in general are afraid of differences despite preaching we are all unique. They are also interested in what they might be able to capitalise on or abuse.
And curious about what they deem to be 'freaks' which is anyone gifted or talented in ways they will never be.
I'm not sure telling anyone would enhance my life in any way so might keep it to myself.
It's a shame you are not afforded that same discretion. As a diagnosed kid, depending on your position within this spectrum and your social and acedemic "performance" takes the anonimity from you. Those who don't need to know are told half information and just invent the rest to suit. Unsympathetic, ill informed and fear mongering individuals are everywhere making vulnerable people feel ******.
HFA get told they are using it as an excuse to get out of things they don't like ...
Being able to mimic and put up with anxiety inducing events to the point of overload is not a choice to avoid an unpleasant dinner. It's how that brain is wired.
I got off topic ... sorry
