Something I think people should be cautious of in this day and age is misdiagnosing people as having autism when really they are just introverts or have some other kind of learning difficulty.
I know the temptation to try and diagnose yourself. And, really, Asperger's in particular is quite broadly defined.
Half my friends could be autistic adults the symptoms are so common.
And I know a lot of kids who are diagnosed as having Asperger's only to have a doctor tell them as adults that they were just depressed, or "difficult".
I don't think people should run from the diagnosis if that is what they have, but don't blindly accept that you have a disorder if you are just a bit different.
It might feel good to have an explanation for what you feel is wrong with you, but in the end it won't change anything.
