Autism Talk

I work in human services, and can tell you that access to most services requires a diagnosis. That said, every state has vocational rehabilitation services for workers with disabilities. Google Vocational Rehabilitation and you're state to find local services.

Also, medication can be effect in managing / reducing anxiety, and to a lesser extent compulsivity in people with autism, so it may be worth consulting a psychiatrist.

Best of luck to you and your son!
