I want to drop out of college

I just found out today that I won't graduate in four years. It will take five. When I declared my major (I went two years as undecided) I was told I'd be able to graduate in time, but that is clearly not the case. My parents are going to be so mad at me. That in itself makes me annoyed because I told them I wanted to take a year off of school to work so I could save up a little money for college and figure out what I want to do. But nope. They made me go and now I won't be able to afford my last year. I won't be able to receive any more financial aid of get any more loans. Basically I'm screwed out of $100,000 with nothing to show for it and all the blame will fall on me. I want to just drop out now. There is no sense in continuing and wasting more money next year (my fourth year) when I know I won't be able to afford it. Scholarships are out of the question because I did poorly for two semesters due to a death in the family. Woohoo life is great.
