My friends 13 year old daughter committed suicide

One of my friends daughter committed suicide because she was being bullied. She was being bullied by an ADULT, someone that should know better, a 33 year old woman! This woman was telling lies on my friends daughter, calling her a whore, saying she was sleeping around with 3 different guys, and she said all this about her in front of a bunch of other people. They all laughed like it was funny. They humiliated her, her mother cussed them all out and left the spot they were at, she told her daughter to ignore it all, spoke to her and tried to let her understand that some people are just horrible people, her daughter cried her eyes out all the way home. Her mother went to take a bath and as she was in the bath she her a gunshot. She tried to save her but it was to late and paramedics couldn't help her either, she died before getting to the hospital. Everything that was said about her was complete lies by the way. And her daughter knew how people would look at her and treat her because of those lies and couldn't handle the thought and took her own life, at 13 years old. What has happen to this world?! I have another friend that has a daughter being bullied also, she is also 13. She's being called fat and ugly and she neither of those things. #stopbullying.
