Bullying is unwanted aggressive behavior among school-aged children involving a real or perceived power imbalance that is repeated over time. Bullying can negatively impact everyone involved, including those bullied who may experience depression, anxiety, health issues, and decreased academic performance. Witnessing bullying can also negatively impact children's mental health and increase risks like substance abuse and suicide. It is important to determine if a child is being bullied or experiencing other issues through open communication.
