Damn! This is a depressing thread. While reading the comments, I was trying to formulate my position, thinking back about things I had done or not done. Yang Bang, you kinda hit it on the head. I seriously doubt that someone at the point of suicide is thinking about courage, how its going to look, what someone will think, that sort of thing. I think they must go beyond a point of reality where their pain is the only thing they are thinking about. Unfortunately, this has been something I have had to think about several times within the last several years because there have been three or four teenage suicides in my town. No matter how well you think you know the family or the kid, you never know the why of it. It really hurts to think about a young life snuffed out because of such unknown internal pain.
As to the original question, I have thought about it, the 'how' of it. I think everyone does. For me I think when I was young it was more about the drama of it. The effect it would have on the ones left behind. There was never any reason for actually doing it. Now that I am older, I find I am thinking about it more in terms of dealing with health issues. To what point, if I had the choice, would my health have to deteriorate for me to consider suicide? Would I do it? Ah, that is the question. I guess I will just have to wait to see what happens vis a vis my health versus that reality thing. So far, knock on wood, it is not an issue.
