You know, that's an interesting question.
With stuff like OCD, and specific phobias, one can "beat" such with evidence and logic based cognitive therapy if one tries (it'll hurt, but that's how it goes). You learn your way through such in other words.
But, with this ASD thingy, I can't see how keeping..., no, needing a routine to function could be a bad thing for I actually can't function without such, no matter how hard and how many times I've tried to. There's nothing to learn, as this is closer to lacking an arm than holding erroneous thoughts over the perceived threat something has.
This is why ASDs aren't a mental illness; there's no component that you can "fix" with logic, thinking, emotional discussion, rational discourse and whatever.
I see no social component in my head, like what other people have; I don't feel anything. Not fear, anxiety, uncertainty or any other emotional affect, I just feel...empty. There's nothing there to fix, just like a person who's born without an arm.
