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.
It's really hard, not to mention very unfair, to be forced to behave in a way that "isn't you".
As far as some of your questions...... no one really knows the future, and there is help available for some of the things you are worried about (like the panic attacks).
My bad experiences started young, even before school. Then when I was bullied in grade school and adult said, "maybe they're teasing you to let you know you're part of the group"....yeah, they meant well, but they were really wrong. Anyway, it was a very isolating experience, but not all people are like undisciplined children or in over their head adults. I have actually met some nice people over the years.
So, don't give up hope because of 19 or 20 difficult years. Your worst fears don't need to come true. You can get a counselor and get desensitized to situations that you currently dread.
Also, just because the school staff or your parents were not understanding that does not mean no one else will be. May you meet some kind supportive people soon.
Peace and strength.
