If you know my personal story, you'll remember that most grade school days ended with tears and on one occasion led me to a failed suicide attempt. I didn't tell my parents when I was picked on because I didn't want to upset them. I thought I could handle it myself, but I was wrong. I should have told them. As I travel around the world talking to tens of thousands of young people, it is evident that no one is immune from being bullied. This epidemic is not unique to North America. Bullying is a global issue. "
