Losing or changing friends is a clear indication of bullying, especially in the teenage years. Also, stopping hanging out with friends could indicate that bullying is taking place within a friend’s group.
If the child is tense or anxious about what may happen the next day at school or anywhere else, he may have difficulty sleeping, and this is conclusive evidence of exposed bullied inside the school.
Spells of crying and sensitivity
If a child or teen is allergic to conversations about school or social activities, this could be a sign that he is anxious about those events, because children tend to run away from discussions around school.
