The Artism Diagnosis

I have an intraverted personality. I enjoy my own company and being with other people. It's not, its just not my comforts on but having spoken to a psychologist and been assessed, it's actually artism. The area where i've had the most difficulty is social interaction with other humans. Things like small talk, in particular, maintain and i can't act. Can i do that? And if i can do that, then i enjoy being alive. So before i begin, so wit my artism diagnose.
