There are many reasons why a child might not tell an adult they're being bullied — feelings of helplessness and isolation, fear of backlash, not wanting to feel helpless or rejected by their peers. If you can, first talk to the child. If they're being bullied in school, reach out to a teacher, or the principal or school counselor. A local counselor or mental health services can also be contacted if someone is acting differently than normal, like always seeming sad or anxious or unable to complete standard tasks. If there is immediate risk of harm, call 911.
