Children as young as nine are struggling with online bullies, according to Childline.
Staff at the Birmingham helpline are dealing with 47 per cent more calls about cyber-bullying than they were five years ago.
And it’s girls and 12 to 15 year-olds who are calling the most to talk about online troubles, particularly on social media.
Name-calling, rumour spreading, blackmail and even death threats are just some of the ways young people have told counsellors they are being tormented.
One boy told Childline: “I’m being bullied on social media by people who call me fat and ugly. I can’t block them because then they’ll just bully me even more at school.
“I don’t want to talk to my teachers about it, I just feel like giving up. I’ve been self-harming to cope but I just want to stop feeling this way.”
