everyone that i've known that has commited suicide never told anyone prior to doing it. It came as a complete shock to our family. The person was either hinging on mentally unstable at the time or went through an extremely traumatic event. While all suicide threats should be taken seriously, i find those who actually bite the bullet do not want anyone to stop them, thus they keep their thoughts private about it.

Those who threaten it constantly just want attention and need a psychological evaluation.
