No one can tell someone how to write a poem about cyberbullying. It has to come from the heart. If you are the one being cyberbullied then say it from the heart and work on the poem until you are happy with it and it expresses your feelings. If you are not being bullied, but want to write a poem to help those that are bullied then you will have to either research bullying on the internet or speak to some young people that are being bullied and ask them what they feel about it.
