Your personality is influenced by many factors. Experiences, surroundings, and genetics all have an impact on personality. How we perceive the world, our attitudes, thoughts, and feelings are all part of our personality. People with healthy personalities can cope with normal stresses and have no trouble forming relationships with family, friends, and co-workers. A personality disorder may be present when a disruption in one’s thinking style leads to a disregulation of life, such as the way they think and act, and it impairs day-to-day functioning. A personality disorder can affect how people think about themselves and others and affects how they control their behavior. Someone with a personality disorder will typically engage in repetitively behaviors that others find offensive or problematic and yet will see anything wrong with their behavior.
