Oh sorry to hear KD, that is awful news.

I've been in the same situation before, it really sucks.
I know the job market is incredibly thin here in Michigan these days, but there are agencies out there that will try to help you to find another job doing what you're skilled at, even if you don't have a home address. And if you don't have any friends/relatives to stay with, there are shelters around the Ann Arbor/Ypsilanti area. It's much too cold here to try to stay on the streets right now.
Let me know if you need any numbers to these places, I'll find them for you. If you're in need of internet access for job searching or e-mail or anything, the local libraries usually have computers that you can use.
I hope your luck changes for the better, keep in touch and let us know if you need any information, we'll try to help where we can.
