Nightmare Over For Twins
Sleepless nights and panic attacks - bullying can have a devastating impact on its victims.
Some children have told us how they have stopped eating, skipped school and even locked themselves in the toilet during breaktime, to avoid their tormentors.
Two sisters we have spoken to have revealed how things got so bad for them, they decided to be educated at home for two years.
The girls were just five when they started being picked on. Five years on, they are back at school, but are still recovering from their ordeal.
