And if so, how did they react?
I've never really told anyone specifically that I am a schizoid, I talk sometimes about being an introvert and not socializing, some of which they can sympathize with but I never go into any greater detail. I don't think they would really be able to understand it and its hard to really describe to someone really what it means to be a schizoid since simply stating I hate being around people doesn't really do it justice in my mind.
The problem, as it is with any disorder, are the generalizations and false stereotypes people assume with you.
