How do you address bullying at school?

First thing is to MAKE school officials aware of the problem. For instance, the school counselor, principle, any teachers. Also, parents needs to have the issue made known to them. Talk to anyone that will listen. Always involve a trusted adult. Discuss issues with a close friend. Make someone listen.

If the issue is being made aware to several trusted individuals, the more likely the problem is to be taken seriously, rather than a record of just 1 (one) account of the issue.

Second is talk to someone that is trustworthy. Express your feelings and struggles.

The worst thing to have happen is that the student didn't feel he/she had anyone to talk to or no one would listen, and the school leaders were never made aware of the problem, before its too late.
