Our personality is the collection of characteristics that make us distinctive as people. How you think, how you feel about stuff, how you behave. This develops and adapts as you grow up and have different relationships and experiences. Sometimes when we experience difficult or traumatic events in our life, it can affect not only our mental health, but also our developing personalities – which can sometimes lead to personality disorders. People with a personality disorder display more rigid thinking and reacting behaviours that make it hard for them to adapt to a situation. These behaviours often disrupt their personal, professional, and social lives.
