I would have agreed fully with you for most of my life, but having now lost half a dozen friends to suicide, I think we're making a big mistake by not talking about it honestly and openly. Not only is it much harder for the friends/loved ones who are left in the dark about what happened, but it misses opportunities for learning and understanding. Most people who have never been ready to kill themselves have no idea what it's like, the hopelessness, the weariness, and worst of all the lies your mind tells you.
I do insist on being classy and respectful, particularly for the family members, but I wish as a society we would talk openly and honestly about these issues instead of high opacity implications.
