A young guy slashes his arm up severely. He starts recording video and talking, showing a bedroom floor literally covered with his blood. He explains that he did this to himself so he could "go out in a special way." He's clearly manic. He paces back and forth across the room and laughs as he clenches his fist to see his blood "spurt out everywhere." The video ends with him saying that he can't breathe and is going into shock.

(After spending hours trying to dig up backstory on this video, I've come up with little information. The only info that I've found:
Justin (guy in the video) posted on 4chan that he was going to kill himself. He titled this video "Dying in a novel way" and uploaded it to YouTube on December 25, 2016 (quickly taken down). Apparently Justin had been self-harming for a while, ie cutting. I've seen posts saying he survived because he ended up freaking out and called an ambulance, but no one has any proof to back up that claim so I don't know whether he survived or not. If anyone knows or has more info about him please comment if you have actual proof)

*Update* after some more digging, I found a chat log between Justin and a friend. I'm positive this is him. He's telling his friend that he's scared to do it, he knows it's gonna be painful. He tells the friend that he'd "pumped himself up" and went to town on his arm. He changes his handle from "j man" to "Justin is dead". He tells the friend to rip the video of him bleeding out from YouTube before it gets taken down. His last words to his friend:

Justin is dead: this is my final goodbye
Justin is dead: I hope you have a great life
Justin is dead: im happy to go to another realm
Justin is dead: bye
