I accidentally saw this definition and I don't agree that most people are like this. In fact, people who are victims of childhood abuse tend to be shy, anxious and people pleasers. So I was surprised when I read this

Complex PTSD (sometimes called “Disorder of Extreme Stress”) is found among individuals who have been exposed to prolonged traumatic circumstances, especially during childhood, such as childhood sexual abuse. These individuals often are diagnosed with borderline or antisocial personality disorder or dissociative disorders. They exhibit behavioral difficulties (such as impulsivity, aggression, sexual acting out, eating disorders, alcohol or drug abuse, and self-destructive actions), extreme emotional difficulties (such as intense rage, depression, or panic) and mental difficulties (such as fragmented thoughts, dissociation, and amnesia). The treatment of such patients often takes much longer, may progress at a much slower rate, and requires a sensitive and highly structured treatment program delivered by a team of trauma specialists.
