Everyone is different in many ways. Some people cope with abuse differently, and one of those ways is posting a video on the internet. But she could not do just that, that video was not "coping with it". She was going to commit Self Delete. She had been bullied a great portion of her life and could not handle it anymore. She made a mistake as a child, and others were not there to support and help her. Only to degrade her and make her life a living hell. That poor sweet girl is dead because of the abuse that she went through, and could not take it.
This should be a reminder, not a "blow it off because it happens alot". A reminder that you don't know what people are going through, so it is best to be that shoulder that others cry on. Or that person people want to talk to. Not a bystander who doesn't give a stuff. Have a heart.
