A personality disorder is a mental illness in which you have a fixed and unhealthy way of thinking, functioning, and acting.
4 personality disorders:
Antisocial personality disorder: It is a mental condition in which a person continuously disregards right and wrong, as well as other people's rights and feelings.
A borderline personality disorder is a psychiatric condition in which a person is unable to keep his/her emotions in check. Increased impulsivity, a shift in how a person feels about themselves, and deterioration in interpersonal connections can all result from a loss of emotional control.
Histrionic personality disorder: A person with a histrionic personality disorder who is emotionally unstable has a distorted sense of self and has a strong desire to be noticed.
A person with a narcissistic personality disorder has an exaggerated concept of self, a strong craving for excessive attention and praise, troubled relationships, and a lack of empathy for others.
