You can not kill yourself just because some idiot wrote something on twitter..
From what is written on the article, it is more because of
- The letter that were sent to her parent, informing them she was having non-Muslim boyfriends
- Her own guilt at what she did, because she was not at all an ex-Muslim if what is said on the article is true.
It seems the only link with Facebook here is that it helps stalkers to stalk you.
