There are apparently deleted twitter comments, including a photograph of her holding Xanac (something like that) tablets. One apparently says, "You win," and other suggests that she's gonna do something to "end her misery."
Therefore, I'm assuming it was an attempted suicide.
It's pretty horrible that people can be so cruel and brutal. It doesn't matter what she says (apparently some nasty crap about NZ has annoyed a lot of people).
For PP asking who she is, she's an NZ ex-pat, ex-model and one of the judges on Australia's Next Top Model.
