Yes, it sucks to have autism, even a high-functioning form. There is no denying it. The worst part is that 'normal' people seem to think that Aspies and Auties are incapable of learning, growing, working, and maintaining relationships, and they will try to convince us that this is our unavoidable fate!
In cases like mine, the diagnosis was both a relief and a release - I finally understood why life sucks for me, and I'm now better able to deal with it. In a way, having an HFA has made me stronger. Since I never new that I was supposed to be unable to cope (according to the common perceptions of autism), I simply worked harder and smarter to overcome what I thought was the rotten luck of being born into a dysfunctional family, being stuck in school systems that favor only jerks and jocks, and working in a job market full of slackers and self-serving suck-ups.
Proving to myself that I could succeed before learning that I wasn't supposed to succeed made all the difference.
