There seems to be more to the story than her just getting upset over a Facebook ‘bullying’. She seems to be a very troubled girl and I doubt the NY City ‘fashionista’ life helped much.
I’m sure she led a very “dramatic” life and was up on all the useless pop culture trivia.
At that age very few problems are insurmountable. Nothing someone says to you should be cause for suicide, and I’ve had people say awful hateful things to me, some of which were true and I deserved.
