Hi and thanks for writing to me.
I'm sorry to read that you were upset last night, but it's good to know that you had your Mum with you. I just wanted to let you know as a starter that you could block these so-called friends so that they can no longer see your Facebook page, or you could de-activate your Facebook account.
How would you feel about speaking to a teacher about what has happened? Maybe your Mum could go with you to school when you speak to the teacher? No one has the right to be abusive in any shape or form and the behaviour of these boys and girls is unacceptable. There might be more young people being bullied than those doing the bullying.
Maybe you and a few good friends could start off an anti-bullying group at your school? You could speak to a teacher about helping to organise this. Your school should help support you and be proactive in helping victims of bullying.
Have a look at Beatbullying, this website provides support and help for those who are being bullied. For more information about bullying check out the ChildLine Explore section.
I hope this helps
Sam
