Can Someone Please Encourage Me Or Something?

I need some advice, inspiration, something or anything positive. I graduated from from college with a degree in nursing back in 2004. The crazy thing is that i'm still not a nurse. I've taken the NCLEX exam 8 freakin' times and failed all 8 times! That test is $275-300 per test! So I've spent well over $1600 on this thing. Not to mention those Kaplan courses that cost $400 per session. I'm flat broke, living with my aunt, and making $11 an hour as a nurse tech. And now I think i'm starting to get depressed because I don't go anywhere, plus basketball which is my passion doesn't give me any joy anymore. I don't want to say i'm suicidal or anything, but if I died tomorrow it wouldn't be a bad thing for me because I feel so unaccomplished in my life. Everybody keeps trying to get me to take that test again, but I don't have the desire or will to study 1 word of medical terminology anymore. Matter of fact, I don't know what the hell to do since i'm thinking about calling it quits on this nursing thing. $40k's of a college education just wasted for nothing! Please can somebody, anybody give me some advice on what I should do. I just feel like a complete failure right now, but I did nothing to cause it! Somebody please give me some encouragement or something.
