A personality disorder is a type of mental health struggle in which someone has rigid and unhealthy patterns of thinking, functioning, and behaving. Someone with a personality disorder may have trouble perceiving and relating to situations and people. This causes significant problems and limitations in relationships, social activities, work, and school. Some people with personality disorders may not realize it, because their way of thinking and behaving seems natural to them. They may also blame others for their challenges or insist the person approaching them is the
one with the issues. Because of this, when offering support, it is important
to set your own boundaries and recognize professional help is always recommended. When having a conversation about getting help, remain firm but nonjudgmental, as shifting rhetoric away from blame and toward a place of caring is more effective.

Please note all of these disorders can be conceptualized as spectrums along which an individual falls and moves, and no group is defined by
its symptoms. Just because antisocial personality disorder (ASPD) is characterized by lying, it does not mean all people with ASPD are liars.
