mrd, I'm sorry that money is so tight for you right now. I have somewhat the same problem, I have enough to pay my bills, but not much for fun stuff. But I'm not complaining because I still can afford cable.
I've been looking for a part time job, but all the ones that would fit my schedule seem to in retail. Not that there is anything wrong with retail, but I've never worked a retail job and I'm afraid my feet wouldn't last. I've always had cushy sit-down jobs.
