Am I a Loser? How pathetic do I sound?

Well at least you got to vent to someone. I wouldn't stress it too much. Yea things aren't going the greatest, but at least you're not quiting. There are a lot of people out there in your position and there are a lot of people who have it far worse. A lot of people cannot even afford to go to college or were unable to finish high school because of whatever reason. Just try to find the bright side of things and look forward to the future.
