Amanda Todd, a Vancouver-area teenager who posted a story to YouTube last month about being cyber-bullied, was found dead Wednesday night in Coquitlam, Canada. Authorities believe she committed suicide.

Amanda's video tells a heart-wrenching story of the bullying she was subjected to -- both online and off. "In 7th grade," she begins, sharing her message on cue cards, "I would go with friends on webcam [to] meet and talk to new people." At one point, a stranger flattered her into flashing the camera.

One year later, a man contacted her on Facebook, threatening to send around the picture of her topless "if [she] don't put on a show." Terrifyingly, the stranger knew everything about her: her address, school, friends, relatives, and the names of her family members. Soon, her naked photo had been forwarded "to everyone."

Amanda developed anxiety, depression, and anxiety disorders, she says in the video, followed by a path into drugs and alcohol.

On September 7, Amanda posted a nearly nine-minute YouTube video where she tells the story of her repeated harassment by bullies on a series of notecards. In the video, she admitted that she had previously tried to kill herself twice.

The Vancouver Sun reports that Amanda was a student in Grade 10 at the Coquitlam Basic Alternative Education school.

The principal of the school confirmed her death and said that she had become connected with many since she transferred to the school in the middle of last year. 'It is a very sad case,' Paul McNaughton told the paper.

'I can tell you we feel we tried everything we could to help her when she came to us.'

R.I.P. Amanda.
