A crutch is a tool to replace something you aren't able to use. Those who don't know they are on the spectrum don't even know that they even lost something. They get along crawling or hopping around. I'll take that crutch. And all this depression and "anti-social" behaviour, isn't that because of the crutch or lack of it? Being the one who's always trying to catch up will make you frustrated and angry: about yourself and the others.

I think you'd be pleasantly surprised by most psychotherapists. They see their job as helping people feel better and function more effectively in the world, and they don't really distinguish one as the means and the other as the end. Each can be justified in terms of the other, so it's always both. I'm sure you could work productively with a psychotherapist even if they're inclined to be more sympathetic to you than you would like.
