I've never been good at the whole "saving" thing. I was fortunate enough to have a dad who was helpful:
As long as I was 1. Unemployed and looking for work, 2. Unemployed, looking for work, and going to school (thanks to grandparents' college fund they created when I was born), 3. Employed part-time and going to school, or 4. Employed (part- or full-time) and not going to school, then I wasn't charged for rent or food. It sucked having to move back home, but since it was only me, it wasn't too hard on my pride.
I still paid for my gasoline and car insurance once I got a job, but the remainder of my (crappy, PT retail) paychecks went to bills.
Calling my bank and asking for help also, er, helped. They closed the cards, for one thing, so I wouldn't spend anything more on them. (Not that I could, since they were practically maxed out as it was.) They also asked me how much I was making per paycheck, and we figured out some payment amounts that would work based upon how much I made and how much I owed. For 12 months, I was racking up no interest on my debt, and my payments were the same each month - provided I made each payment amount on time.
Now that I've pretty much got my feet back under myself, I'm going to look into this curious "saving" concept I've heard so much about.
