<human>: Basically the police are being no help whatsoever and I'm at a complete loss as to what to do now...

Last night as I was leaving work (at a mall,) I was exiting through the back, and I go through a service lot that has really piss-poor lighting. I had just cashed my check from when I was working open-close every day of the pay period due to it being around Christmas time...So it was an *extremely* big check for me. It was essentially 80 hours regular and around 30 overtime hours, so it's something I'd been looking forward to.

Anyways, as I was leaving the mall, I heard hurried footsteps behind me, and as I turned around all I had time to see what a fist in my eye, I spun around and landed face-first on the pavement, and then the guy fished my wallet out of my pocket, took over $1000 in cash out of it, threw my wallet at my head and ran off. 

I know it's stupid to carry that much money around but I just didn't have time to go to the bank before then...I've filed a police report, but as I didn't get a good look at the guy and there's no cameras back there, on top of it being extremely dark, they're saying there's essentially absolutely nothing they can do, and my company can't just cut me another check.

Now I have a rent check that's going to be so late I might be evicted, and possible hospital bills, on top of every day expenses that I have no way to cover over the next 2 weeks.

Sorry if this seems kind of jumbled, I'm still kind of in shock and have never had ANYTHING like this happen to me before, so I don't really know how to handle the situation or what to do/where to go from here......Any advice would be great.

Here are some photos of what he did to my face:

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I got mugged and had my entire check, which was much more than I normally get paid, stolen from me, with no leads nor help from anyone in authority. Completely at a loss.
