Schoolgirl Amanda Todd Documented Bullying On YouTube Before Suicide (VIDEO)

A schoolgirl who was driven to suicide by bullies had documented her heart-breaking story in a YouTube video weeks before her death, it has emerged.

Amanda Todd was found dead on Wednesday, five weeks after she posted her video on the site. In the footage, which was uploaded in September, she describes her personal hell, of attempting suicide by drinking bleach, and being beaten up by a gang at her Canadian school.

Amanda was 15 years old when she killed herself

Her mother has now said she wants her daughter's video legacy to be used to help other victimised teenagers.

In September, 15-year-old Amanda uploaded a nine-minute-long video titled My Story: Struggling, bullying, suicide and self harm.

Throughout the video, Amanda remains silent, telling her story using a series of placards. One particularly heart-breaking message reads:

Amanda's torment started when she was in Grade 7 (the Canadian equivalent of Year 8), when a revealing photograph of her made its way around her school. The owner of the photograph tracked down her address, friends and family and threatened to further circulate the photo.

The teenager discovered the photo had been sent to everyone at her school after the police paid her a visit at her home in Vancouver. Amanda tells the camera how she suffered anxiety and "major depression", writing:

"I then moved and got into drugs and alcohol. My anxiety got worse... couldn't go out.

"I can never get that photo back."

Amanda in happier times

Amanda was eventually driven out of school and moved to a different area.

She then tells how she became close to a boy who had a girlfriend. After they slept together, she was hounded at school by the girlfriend, who eventually beat her up - while other students filmed the attack.

"I wanted to die so bad," she writes. "When [my Dad] brought me home I drank bleach.

"After I got home [from hospital] all I saw was on facebook - she deserved it... I hope she's dead... She should try a different bleach, I hope she dies this time and isn't so stupid."

After seeing the vile messages, Amanda tried to kill herself again.

"I felt like a joke in this world... I thought nobody deserves this," she says.

In the description of her video on YouTube, Amanda writes:

"I'm struggling to stay in this world, because everything just touches me so deeply. I'm not doing this for attention. I'm doing this to be an inspiration and to show that I can be strong.

"I did things to myself to make pain go away, because I'd rather hurt myself then someone else. Haters are haters but please don't hate, although im sure I'll get them. I hope I can show you guys that everyone has a story, and everyones future will be bright one day, you just gotta pull through. I'm still here aren't I?"

Her posthumous message has now been seen by more than 55,000 people. Her mother, Carol Todd, told local paper the Vancouver Sun: "I think the video should be shared and used as an anti-bullying tool. That is what my daughter would have wanted."
