Typically when people talk about it they're not serious, its more of a cry for attention/help. Those who are serious about it, you wouldn't be able to tell it is on their mind unless you pay very close attention. I've had an experience dealing with suicide and the person who did it seemed to be the happiest guy I ever met. Of course there are exceptions.

The attn getters are dumb, so are those who make that decision in life. Travel the world and see the conditions that others live in then try and complain about how bad you have it.
