Yes. Generalized Anxiety Disorder is common for those of us with Asperger's. We are often in a constant hypervigilant state, maybe because we've had so much experience with people getting angry at us "out of the blue," because we made a social error of which we were unaware. And we also suffer from black-and-white thinking, where all is fine or all is lost. It's like we have circular ruts in out heads which trace over paths of worry again and again. It can make daily living overwhelming.
