Bullied at school for his dwarfism, 9-year-old Quaden Bayles sobs uncontrollably in the back of his mother's car -- saying to the camera: "Give me a knife, I want to kill myself." His mother, Yarraka Bayles, from the Australian state of Queensland, posted the heartbreaking Facebook Live video this week to raise awareness of the impact of bullying. "This is what bullying does," she said in the video. Among them is Australian actor Hugh Jackman, who posted a video message to Twitter telling Bayles: "No matter what, you've got a friend in me." "Let's show Quaden and others that there is good in the world and they are worthy of it."
