We all have real limits: full-time jobs, family obligations, and yes, some of us have disabilities or mental disorders as well, yet many of us make the time to choose some kind of happiness. Be it a hobby or an interest, being a member of a club or a church choir or a baseball team, or simply being around ppl whose company we enjoy, for examples. I understand that those with Aspergers have problems in social situations, but that doesn't make them incapable of relating in some way with others.
You surely have talents or interests or a curiosity about certain subjects that you can share with the world.
