I've read people on the spectrum are at high risk for certain comorbid psychological issues/conditions/disorders, which means that recognizing the AS/ASD and pursuing positive steps (e.g. education, therapy) to help you understand the ASD and to learn to wield it as a strength rather than a weakness could seriously help your other issues/diagnoses.
It is true that there is no pill for AS/ASD. Personally, I wouldn't take one if there was. I believe it adds more than it subtracts from our lives in most cases. The potential co-morbidities, though, have to go (e.g., depression, anxiety, etc.). They add nothing and take everything.
I understand the situation with disability and the difficulty integrating at work, but I encourage you not to let fear of losing that support halt your progress as a person. There are always risks on the road to happiness, but nothing venture - nothing gained. If you did lose your disability, then perhaps you could find a job working at home or in a secluded office? The bottom line is that you may have to choose between your disability check and moving on with your life, and that is a decision only you can make. Sometimes the crutches we lean on while recovering end up holding us back, and sometimes we really need the crutch. It is difficult to know which case it is.
