I wouldn't think my life was hell without my "belief system"(it's kinda funny to call my Christianity like that, but that's OK I think you deserve some answers.)
I would call my life "meaningless", I mean any life "meaningless"
I love my wife, my children to death, but you know. People work all day to support family, make payments, some happy moments, some sad moments, some stressfull moments,,,etc.
in the end it's always same, "we all die at somepoint"
Good person, bad person, smart person, doesn't matter we all die and go to ashes.
What do you think?
