Every story you read is sad, you should never really delve deep into why they did it, but remember what their good points are and not remember what bad choices they or others made. I recently watched a documentary (inner film maker showing) which shows a suicide forest in japan, this isnt for the faint hearted, especially the end but it really opens your eyes to things, the person the documentary is following is very influental, you can check it out here if you like

I think if we just actually talked to these lonley people and show an intrest in them and be friends with them then maybe just maybe you can save a life, a life which has so much potential to it. As a personal thing i know how it gets to be bullied and i know how it gets to be in the situation to want to end everything and it sucks, in the end life will turn out better, but in that situation you dont think like that so people belive that ending it is the only option, this is why we as people need to show intrestest become friends with others make them feel included, make the feel wanted. This is a quote from the video link i posted: You think you die alone, but that's not true. Nobody is alone in this world. We have to coexist and take care of each other.
