I don't think sociopaths or narcissists can be helped because they don't think they need help. Most people who are advoidant can't be helped because they usually avoid going to therapists. (I was avoidant but now I am more borderline personality disorder I guess) There are also people who are court ordered who have to be there who really don't want help. Then there are others who just want to vent but don't really don't want to change. That is my opinion
