I want to go back SO bad.

I just checked my email and there was a message about internship positions available in New Orleans. I want it so much but know I can't leave school. My heart is seriously torn right now. Can't you just picture it? Living between ninth ward and downtown, ministering to the community and students, and gutting houses! Man, I want to be there.
But I have class. And I have already managed to bomb my first quiz in mate today. I would have gotten even more wrong if I hadn't thought to myself, "The answer is always C." Well, maybe it was just a lucky guess.
New Orleans. Can't I just go? a year? six months? maybe?
