There have been tons of suicide blogs over the years and this just another in a long line. They are created by people who either need attention or are trying to find some kind of self worth in the way of strangers pleading with them to not do it.
If you have no idea what i am talking about there is a blog called 90dayjane in which a woman claims she is documenting the 90 days prior to her planned suicide. Her blog consists of day to day commentary of her life peppered with assurances that she isn't doing it for attention and full of comments by strangers pretending that they give a shit.
So how do i know it is a hoax? If you look on her blog she says;
I am going to kill myself in 90 days. What else should i say? This blog is not a cry for help or even to get attention. It's simply a public record of my last 90 days in existence. I'm not depressed and nothing extremely horrible has lead me to this decision. But, does it really have to? I mean, as an atheist I feel life has no greater purpose.To me this stinks of a religious person trying to paint atheists as immoral, materialistic machines with no self-worth. surely an Atheists greatest purpose is to stay alive. When Atheists die that is it, There is no reunion, There is no handshake with god and there is no eternal happiness. the Atheist believes we get one life and when it's over it's over.
So logically speaking, An Atheist is far less likely to kill themselves for no reason than someone who believes death is nothing more than a transition to a better place.
