She told us how she ended up in hospital after being attacked by a gang of girls in the school playground.

"I am due back to school today and I am really worried," she told us. "The girl who attacked me is also due back, after a five day suspension."

Danielle has been bullied before - but this was by far the worst incident.

Her mother told us: "I went down to school the day Danielle was was hit and I was so shocked when I saw her that I didn't question the length of the suspension.

"Now, the week's gone so fast - she's back as though she'd done nothing."

What can be done to stop bullying

Bullying "epidemic"

Almost every school pupil in the country has been affected by bullying, according to the government's new Children's Tsar, Professor Al Aynsley Green.

In an interview in yesterday's Observer newspaper, he warned that many schools were "in denial" over the severity of the problem.

What you told Breakfast My son was bullied mercilessly for three and a half years in his junior school. The school gave the bully special counselling, special playground friends, special teachers but did nothing for the victim, my son. There were several other victims who suffered the same fate.

Prof Green, who's the Children's Commissioner for England, points to a culture in society which sees violence as the norm, whether it's on TV or in relationships between adults.

Getting help

If you're being bullied at school, it's important to get help, rather than suffer in silence.

If you feel that you can't talk to your parents or teachers, you can share your problems in confidence with someone from Childline: 0800 1111 - or Kidscape (links to both charities on the right hand side of this story).

Kidscape sum up their advice as: Run, Yell, Tell: if you encounter a group of bullies, get away as fast as you can. Call for help - and tell someone in authority about what's going on.
