Amanda Todd was a 15-year-old girl from Canada.

She uploaded a video to YouTube describing years of bullying that she said drove her to drugs and alcohol.

In the nine-minute video she told her story with a set of handwritten notes.

The recording, described as "haunting", showed the cheerleader going into detail about what happened to her.

She said she was persuaded to expose her breasts to a stranger who then sent the photo to her school friends.

These images were then used to torment her on social media.

The teenager changed schools repeatedly but that did not stop the bullying and she was physically attacked by classmates.

The last cards on the YouTube video read: "I have nobody. I need someone. My name is Amanda Todd."

Just weeks later, Amanda was found hanged in her home, one month before her 16 th birthday.

Thomas Thompson, age 11 from Merseyside, is claimed to have been driven to suicide by bullies at his school.

According to his parents, Thomas took an overdose of painkillers and suffered a fatal heart attack after other pupils picked on him because he was clever, well-spoken and didn’t fit in.

On 18 May 2010, Dominic Crouch committed suicide by jumping off the roof of a six-storey block of flats near his school in Cheltenham. He was 15.

In the note he left his family, hastily scrawled in sloping lines of black ink, he wrote: "Dear Family, I'm so so sorry for what I'm about to do. I have been bullied a lot recently and had a lot of sh*t made up about me that ain't true."

It emerged that Dominic had kissed a boy on a school trip during a game of spin the bottle.

At the time, it seemed little more than a bit of fun amongst friends. But some participants recorded the game on their mobile phones and were subsequently believed to have been passing the images among other friends.

Sophie Lancaster was a 19 year old student, about to embark on an English degree.

She had been dating Robert Maltby, a 21- year-old art student at Manchester, for three years, and they both had a long-standing attachment to the ‘goth’ subculture.

While returning home late on Saturday 11th August 2007, Lancaster and Maltby were subjected to a vicious attack from a large group of people.

The couple were walking home and came across a group of teenagers at the entrance to a park. The group followed them, and some of them suddenly assaulted Robert Maltby without provocation.

When he was knocked unconscious, the gang attacked Sophie Lancaster, who was trying to protect him by cradling him in her arms.

Witnesses revealed that afterwards, "The killers celebrated their attack on the "moshers" by telling friends that they had "done summat [something] good," and claiming: "There's two moshers nearly dead up Bacup park — you wanna see them — they're a right mess."

Both were hospitalised as a result of the attack. Maltby's injuries left him in a coma with bleeding on the brain. He gradually recovered, but was left with lasting brain damage.

Lancaster, in a deep coma, was moved to specialist hospitals, but it became clear to hospital staff that she would never regain consciousness, and on 24 August 2007 her family agreed to switch off life support.

All of these young people died as a result of bullying.

Bullied for making a bad decision…

Bullied for being clever…

Bullied because people thought he was gay…

Kicked to death for being ‘different’…

We hope that by watching this, you may think twice before condemning someone else for being a little ‘different’.

Don’t suffer alone…

Tell someone.
