I haven't graduated yet (althought I'll most likely be done in a year), but I've heard enough to see the diference between a bachelor recently graduated and someone who hasn't studied anything after the hi-school: nothing. Suposedly you've got to build your career through several jobs until you end up getting some seroius wage. Again, the life of man is based on hope. You allways say "meh, I'm fucked but tomorrow will be better". And usually it isn't but oh well, you've got to keep moving. Don't surrender.
I think you should follow your counsellor's advice. You don't have to stay in that job forever. But you must build yourself a curriculum if you want to get a good job. Having no experince is a bad thing. You can't really get a good job if you don't have it (unless you are very lucky and, no offense, looks like you aren't). So go find yourself a qualified job. Most likely you will work harder and maybe even get a bit fewer money than with the hydraulic valves, but I think it will pay the effort in the end.
I must admit that that 1200$ a month is a real problem though. I can't find any way of cutting that 80000 debt in the short term. You can earn quiet a lot of money working on the construction (at least here in Spain), but it's a risky (too risky without social safety or a health insurance) and though job and it won't help you build a curriculum.
Sorry, but I can't be any more helpful
