I don't agree with the "no-one's selfless" reasoning/assumption.

Mania can truly be selfless, in my experience.

Can you really be depressed and have an antisocial personality? I don't believe that. Would be more like a borderline personality then (sometimes emotions hit you hard, sometimes you can suspend that; BP matching personality).

Syndromally antisocial (i.e. warranting a diagnosis; the complete personality) is really almost never feeling much. It's somewhat like negative symptoms of SZ (in some ways) but different: you don't accept feeling that little so you do things to make you feel, a bit like borderline but more extreme because it really takes pretty extreme things.

But I do use antisocial to refer to some SZ or borderline personality traits. But I wouldn't say I have a antisocial personality.

It's used in forensic psychology probably more than any other personality disorder.

But maybe it doesn't matter or they're right. I don't know. I just wouldn't want to be known as a sociopath and I wouldn't take kindly to such suggestions.
