Sorry I didn't see this thread earlier. I can't read all the replies (1. it's late; 2. triggering topic for me). So I'll just throw in my 2 cents...

LoneScout: As you know, there are things in life that are much much worse than death. Your wife (and even your child once he/she will be born) will have to go through living hell if you kill yourself. Do you really want them to experience the kind of great overwhelming and devastating sorrow you're currently battling?

Believe me, I know very well how tempting death can be. But please consider the consequences of your actions. Sometimes doing the right thing doesn't equal doing what we feel is in our best interest.
