I can understand it, but I would never do it. Why? My stepfather did it about 7 years ago, and it absolutely destroyed my mom. She came home to find him literally swinging from the rafters in the basement. I could never do that to my wife. She suffers from depression as it is, and me doing that would push her completely over the edge.
Life can be an absolute bitch sometimes. People are nasty and disappoint you, things don't work out the way you planned, money issues, non-stop work and pressure, etc. However, I do believe that we are here for a reason, and somehow it will all work out in the end. I fear that by taking my life, I will be punished. My ultimate fear is that my punishment would be to return to this miserable world again to live my life again. One ride through this life is more than enough for me. The next time I may not be so fortunate as to where I'm born, and be born into desperate poverty and oppression. There are many people who believe (and I'm one of them) that what we are experiencing now is hell, and that by taking your life you will be punished by having to repeat life all over again. The thought of this is what terrifies me the most.
