I'm still trying to understand why anyone likes that answer, besides it being true. I've had a very good life compared to many fellow human beings who have passed on. Yet I still need religion to help me push through it. Otherwise it's just not worth it. I wonder how my ancestors walked into gunfire than with all their confederate money worthless, had to make a living with one leg. And yet he did, and left an inheritance as well.
Ajax,
The reality of the universe is indifferent to whether or not we like that reality. Whether or not we like reality has nothing to do with what reality is.
You asked earlier how we push on when life isn't worth living. There was only one time in my life when I questioned whether life was worth living, and that was as an LDS missionary. I've previously mentioned that was the only time in my life I was seriously depressed - so depressed at one point I could barely leave our tiny one room apartment without breaking into tears. In a strange way, that horrific mission experience seems to have put other things in perspective throughout the rest of my life, and, in comparison, nothing else in my life has felt as hopeless and overwhelming as that time did. And I've been through some tough times. I remember on my mission thinking that suicide could be an out if it were not for the fact that I'd simply "wake up" on the other side with really PO'd Heavenly Father, and then I'd likely suffer an eternity for what I'd done. That thought kept me going.
I think that unless you are dealing with some overhwelming life circumstance (like a very bad marriage), if you really feel that life, on its own, isn't worth living, then it might be a good idea to get some medical intervention. You sound depressed to me. And if you are dealing with an overwhelming life circumstance, find a way to change it, if possible - and you may need help with that, too.
But if I were to face such a deep depressive outlook that life just didn't feel worth living, I imagine that the fear of hurting my family would keep me determined to hang on. And I believe it would get better, eventually - maybe only with professional intervention, but I do believe it would eventually get better.
