There is an incredible lack of empathy and insight on this thread, in my opinion.
For some people, suicide is not a problem, it is a solution. The problem is their illness --- be it physical or mental.
I have mentioned this before, my friend Frank killed himself a few years back. I miss hanging out with him. We always made each other laugh so much by riffing on each other's darkly humorous and off-color jokes.
But Frank had profound depression. Being alive was mostly agony for him. When he took his own life I felt relieved. He was finally no longer suffering. His pain was over.
I admire his bravery.
