Todd said she "wanted to die so bad" when her dad found her in a ditch. She drank bleach when she went home and had to be rushed to the hospital to have her stomach pumped, she said.
"After I got home, all I saw was on Facebook--'She deserved it. Did you wash the mud out of your hair? I hope she's dead,'" she wrote.
Todd moved to another school in another city, but said the torture followed her through Facebook. Students posted photos of ditches and suggested she try another bleach.
"Every day, I think, why am I still here?" she asked towards the end of the video. "I'm stuck. What's left of me now? Nothing stops. I have nobody. I need someone. My name is Amanda Todd."
Authorities were called to a residence in Port Coquitlam, British Columbia, just before 6 p.m. on Oct. 10 to investigate the sudden death of the tormented teenager.
Todd said in her video that she did not want to press charges against the girl who beat her up because she wanted to move on when she moved to another city and school.
Cheryl Quinton, spokeswoman for the Coquitlam School District, told ABCNews.com, "The family was wanting to pass along that several supports were in place for their daughter on the school, home and community levels. There was a lot of intervention and a lot of support. I know that is the message that they want to convey."
Quinton didn't get into specifics of the timeline, but emphasized that Todd's parents wanted people to know that "there was a lot of support for this student."
Todd was in the tenth grade at the Coquitlam Alternate Basic Education School when she died. School officials would not release the name of her previous school.
Quinton said the death has been "very devastating" to the small school where resources are being provided to students in regards to suicide prevention and bullying.
"We typically, as a school district, don't talk about such deaths but with the family's endorsement we did choose to do so because it is important to point out the dangers associated with social media and cyber-bullying," Quinton said.
