What can you do if your funding doesn't come through?

Right now, it seriously looks like I'm not going to get the scholarship I was expecting. I was told I should get the scholarship, that my program would look impressive to them, but I was supposed to find out last Monday and still haven't heard anything. I emailed my school if there was any update, but have not heard back yet. I'm trying to sort through my options if this falls through. I already quit my job, told other schools I'm going elsewhere, and committed to this school. Is it possible to back out? Can I beg my second choice school for a spot? I wonder if I could get funding some other way...Has anyone been in this position before?
