Why do you end up blaming yourself after being bullied

I would blame my own failure to conform. I would blame myself for being different. For being poor, for being overweight, for being too shy. For not being "normal". Adolescence is a rough time for everybody. People are struggling to find their identity and their place in society. A young mind still places a lot of importance on fitting in. Really, the bullies are to blame for their insecurities and inability to accept their own differences. They lash out at those who are seen to be not acceptable in order to assure their own acceptance, even if only in their own mind. It is never the victim's fault that they are bullied. Even if a person was flawless, a bully would find something to pick at and make them feel insecure.
