Welcome to Fluther.
For another glib answer: I just searched for happiness, and I found 369,000,000 results in 0.45 seconds. It’s on Google. I’ll post a link for you if you need that.
While I don’t want to criticize you while you’re feeling so badly about life right now, you seem to have defined happiness in terms of things you might / should have attained by now. We all want that great job, nice car, home of our own and beautiful girlfriend. (In fact, it seems like half of the women I meet also want that beautiful girlfriend; there’s a lot of competition for beautiful girlfriends, I guess.) But does that mean that we can’t be happy without those things?
You’re currently defining your failure to achieve happiness by your failure to have those nice things that you want. And it’s clear that a 5-hour daily commute to a dead-end job (as you have defined it) is a burden that would weigh on anyone. That, more than anything else, would make me unhappy, to be sure! Not to be trite (on top of glib? that would be unforgivable), but surely you can find another dead-end job closer to home, can’t you? At least that would give you an additional five hours a day to do something that gives you more enjoyment … or prepare you for a better career, find a girlfriend, etc.
You remind me of a very old joke about a cobbler whose shoes were too tight. Every day he would complain about his tight shoes as he made and repaired shoes for others. He would also complain about his unlovely and unloving wife, his ungrateful children, his evil landlord, and the bus driver who carried him back and forth between home and work. At the end of all his complaining he would mention that the only thing that ever brought him any joy or satisfaction at all was to get home and take his shoes off.
One day one of his co-workers had had enough and reminded him, “You have a lot of things that you can’t do anything about, and it’s easy to see why those things make you unhappy. But you make shoes for a living! You fix shoes every day! You know everything there is to know about shoes! Why don’t you just fix your shoes so that they don’t pinch your feet? At least that’s something you can fix in your life.”
The reply was immediate. “What!? And lose my only enjoyment in life? Never!”
