Well that sounds negative, empty, pessimistic and without any rationale of hope, God or love to be found in the world and in life and that my friend is unfortunately a very dark scary place to be so if that's where you are as a human being in your evolution I suggest you seek serious help. He needed help, did not help himself and just because you have a tragic event in your life LIKE WE ALL EXPERIENCE in our own way shape or form that does not justify taking any life, certainly not your own. That viewpoint comes strictly out of my love, appreciation for life, and optimisitic view on things because I have God in my life and life, no matter the flaws, is always better than death.
Like I said to begin with may God have mercy on his soul.
The thing is nobody knows how bad it can get inside a person's head. By that i mean their sanity, their mind, their psyche, whatever you want to call it. For Bill Zeller, suicide was something he comtemplated for years, so who knows how bad it had gotten?
