I am not sure as I have never been diagnosed with anything in the psychological realm, but I have the same experiences as some of you. Everyone says "You look mad". I am not. I am just minding my own stuff and thinking my own thoughts about my own business. My mom once said I was a snob, but in reality it was she herself that was ; making use of the words, "lower class", etc. I DO prefer to be alone and quiet with my own thoughts, but people seem to take that personally for some reason. I admit I am not friendly, but that is not a crime. However, I am not mean either. I leave people to themselves and expect the same, as my signature says.
