Autism, like all "disorders" differs in severity. If you're really looking for help understand all of this I wouldn't suggest these forums. More often then not the crowd around here will suggest going to a doctor, getting medication and help because there is something "wrong" with you. It's a load of bull. Plus, here you'll just get into silly debates with a good some of people who don't have any actual experience with mental disorders, at least not from the perspective of alternative "medication" (and no I don't mean drugs).
I'm not saying they aren't brilliant, just that this place isn't the right place for this.
If this is a big thing to you, something you are dealing with rather then wanting to debate, then google the Icarus Project. As it is made up of people who actually have the disorders and a good mix of people who go through the popular means of therapy, as well as their own.
Icarus is also a lot more then a website, and you can attend meet ups and events (if in your area, or you could start your own group).
Feel free to debate here, but if it's a big deal then discussing it with people who know it first hand might be a better way to go about it. And, don't trust the mental health system, it's a crock of horse *splat* (of course, it does help some people, but generalizing treatment is disgusting in terms of mental health when even the same disorders are individual)
