The tragic 15-year-old had placed a heartbreaking clip on YouTube just five weeks earlier detailing how she was harassed online and bullied.
Now her mum Carol wants the video to help other young people avoid a similar fate.
She told 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".
The black-and-white clip - entitled My Story: Struggling, bullying, suicide and self-harm - was posted to the sharing site on 7 September. It shows a silent Amanda flipping through cards with her story written on them...
Tragic...gorgeous Amanda poses for
a photo on her Facebook page
Revealing one sentence at a time to the camera, she tells how her troubles began when she discovered chatrooms. Lonely and keen to meet new people, she got talking to guys online and was showered with compliments by one in particular.
He asked her to flash her boobs at him which she did just once - but it was enough.
A year later, the unidentified man contacted her on Facebook threatening to circulate the image if she didn't perform a show for him again.
When she refused, he circulated the revealing photo to her relatives, friends and schoolmates.
"I can never get that photo back", she writes on one card.
Shunned and called names by her classmates, she switched schools. But the bullying continued.
Later, she was beaten up by a group of teens in front of her new school and the attack was filmed.
Feeling isolated and desperate, Amanda went home and drank bleach.

But recovering in hospital, she was horrified to see that the bullies had posted pictures of bleach bottles online with captions like: "She should try a different bleach. I hope she dies this time and isn't so stupid."
On one heartbreaking card, the former cheerleader writes: "Every day I think why am I still here? ... I have nobody. I need someone".
The pretty brunette was discovered dead at her home in Port Coquitlam at 6pm on Wednesday.
