Bullying is a behavior that is often learned in response to stresses in the bully's world. These stresses could include strained parental relationships, poor academic performance, unsupportive peer networks or anxiety regarding physical appearance. While bullies give off the appearance of confidence, it is often the case that their actions are driven by insecurities. Harassing and overpowering others gives bullies a sense of superiority, making up for the lack of control in some other part of their lives. Surprisingly, many bullies are often motivated to abuse others because they have been victims of abusive behavior. The anger that they feel as a result of being hurt is directed toward other individuals.
