Am I a deluded sinner, because I'm happy even though I'm in debt?

I know this sounds like a stupid question, but I know of many people who feel that they aren't allowed to be happy because they owe money or don't make enough. I'm not an irresponsible person. I have 2 jobs and my wife has 2 jobs but it still isn't enough money. I laugh and joke with my children. I call them silly names and make silly sounds to entertain them. I don't see why I need to go around with a "woe is me" kind of attitude. Am I missing something here? Should I be more miserable because I owe money?
