Various personality disorders might respond differently to psychedelics. For instance, people with histrionic personality disorder (excessive attention-seeking and emotional overreaction) or borderline personality disorder (emotional instability, intense relationships and fear of abandonment) might feel worse or more unstable. And those with schizotypal personality disorder (social anxiety, odd beliefs and eccentric behaviour) could become more paranoid. People with narcissistic personality disorder (excessive self-importance, lack of empathy, and need for admiration) may struggle with the self-reflective nature of psychedelics because they often have a hard time handling criticism.
