The parents of a 6ft 4in 13-year-old girl from Rutland have called in the police after bullies used an internet chat room to threaten her.
Caroline, who is 6ft 4in, says she is bullied for being tall
Caroline Stillman was taken out of Uppingham Community College in November after a bullying campaign made her ill.
The family say bullies have abused Caroline via the internet, telling her on one occasion to "go kill yourself".
She says she suffered name calling, was pushed downstairs and threatened with scissors in class, just for being tall.
Caroline has Marfan syndrome , a genetic condition which can cause excessive height.
Her father, Bill Stillman, said the family were forced to remove her from the school as she was being sick after meals because of the bullying.
Caroline said she was "angry" that she was having to miss out on her schooling.
"I want justice because they're still getting their education, having friends and I'm having to stay at home," she said.
Head teacher Malcolm England said bullying had no place at the school.
"We need to tackle these things openly. The school has an anti-bullying charter and we are very upfront with pupils.
"They know we won't tolerate bullying."
Mr England said the school was working with the family to help Caroline return as soon as possible.
Police are now investigating the online threats.
