Everything short of physically restraining him to listen to your ideas, right?
What do you mean?
My friends are an important part of my life, losing them would be like having no reason to live for.
Sorry if Im saying this, but this thread doesn't make much sense to me. And I never found myself in a situation where someone I care about, would want to commit suicide. There must be some reason that has pushed them this far, if it has then I would consider myself a really bad friend, because if I didn't help him/her in those difficult times, how the hell would I be able to do that when he or she already made the decision?
I know, my ideas sound like contradictions.
