, man i had the same depression you have, in 2009, was my last high school year, and i was choosing what college i wanted to do,
so at this point i stop to worry about the college, and finished my school year in december (in brazil it ends in december
)
after two months of vacation, december and january, i decided what i want to try on the exams for college in nov/2010 now im studying for it, and no depression :P
I see a little similarity, with u, i live on a little town (about 130k inhabitants), and my family is a middle class in brazil.
My suggestion for you: do your engineers college and come to brazil to work on volkswagen, Fiat, etc. you can have the cars of the year, and earn a lot of money!!! :P
