1998 Honda Civic Got timing belt replaced, now head gasket

I got my radiator replaced about 7 weeks ago by an independent mechanic, plus some regular maintenance (though he did not replace the thermostat) for about $400. A few weeks later, the water pump burst. I guess he left an air bubble in. He did not replace the thermostat. I broke down far from home, and just managed to refill it with enough coolant (with the help of a mechanic who helped me on the side of the road) to to get it to a honda dealership which was luckilly near where I broke down. The water pump burst. The first mechanic assumed no responsibility. I paid about $600 here to get the thermostat, water pump, and timing belt replaced. Now it is 3 weeks after that, and my check engine light went on and I had trouble starting. I called the dealership and they said to bring it in, so I was planning to go to the one which was local to me, and it overheated! I had to pay for triple a ($90) and get it towed to the honda dealership. Now I understand from talking to my friends that the timing belt may have caused the burst head gasket (which I specifically asked to have checked at the first break down at the dealership far from my home and they said were fine) but the dealership will find a way to blame me and charge me for the head gasket. I have no more money available for non-essentials ( just graduated college and am in debt, and have about $700 which I need for rent, food, bills etc. And the economy is bad and I'm having trouble finding a job), and I have heard the head gasket can be thousands of dollars, and maybe I should just cut my losses. Unfortunately, I am moving next week back to my hometown, which is 1,000 miles from where I currently live, and I was planning on taking my things with me- now I don't know how to get home!
