What do I do? Help Me.. Financial problems... Legal Problems?

I am in financial crisis.. I lived off of small paychecks most of my life, but in the last couple of years fell into a way better paying field of work in the refineries and made much more than the average person... With the extra compensation came extra bills, I was buying a nice newer truck from a joe schmoe used car lot, I decided I would buy some wheels from rent a wheel, knowing that I would have them payed off in less than a month... well does life have a funny way of playing games with people, my nice big new truck broke down, the car lot gave me the cold shoulder saying that it was my duty to repair the vehicle i had only had for 3 months, and I didn't have the money at the exact moment that they told me this.... I was ahead in my payments on the truck and they still put it up for repossession... saying that my insurance had lapsed... which would not have been a problem except It was sitting at their shop when they did this. My wheels were on the truck.. they told me I couldn't have them, I told them they belonged to rent a wheel, they weren't mine, They said i would be arrested for trespassing if I went on the property, I was under the impression that I had 30 days before they could do anything with the vehicle, and waited a foolish week before letting rent a wheel knew what was going on, during which time, i Managed to basically lose my job struggling for a ride to work.... Rent a wheel contacted the car lot and they said they had auctioned the truck off only 10 days later, and the wheels were on it, and I had never made any attempt to get the wheels. It has been a couple of months, I missed some payments and they had me come into rent a wheel and renegotiate my terms, told me that I was facing 10 years imprisonment or 10,000 dollar fine minimum for theft of rental property.... said If i was one day late on one payment they would process all there papers, the re-agreement ("where they were trying to help me") and everything to the courts. I am 2 payments behind today. I have no money to pay, times are very hard, bill collectors like talking to me. I owe rent and etc, I probably have 15,000 in debt and not even a mortgage or car loan right now.... I don't know what to do, and I am not making enough money to hardly pay for the necessities, I want to pay my bills. I had good credit before all this.... I traded in a good car for the truck that was paid off, and i basically gave my other truck away to help a family member.... and now I don't even have a good vehicle... Im about to just curl up in a hole and give up. Please someone with good advice, help me out..
