Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.

Asking questions when you don't understand is not dumb. It is a really good way to communicate, and to learn something.
Hang in there. I hope you find friend(s) who know how to tell you kindly when they can't answer your questions right when you ask them.
Best wishes.
You could think of it like this. Your mind is very analytical and you need to keep exploring and seeking answers for a deeper understanding, just like the stereotypical portrayal of a genius. The image of a genius is basically just a high functioning autist.
A lot of people who had autism have been behind many of the major inventions and developments in society because they didn't think like other people.
