Recognizing the warning signs is an important first step in taking action against bullying. Not all children who are bullied or are bullying others ask for help. According to StopBullying.gov , signs a child is being bullied might include: unexplained injuries, lost or destroyed clothing, books, electronics, or jewelry, feeling sick, faking illness, changes in eating habits, difficulty sleeping, declining grades, feelings of helplessness, and self-destructive behavior.
