Thoughts are with you and your DH, Gibby. I was homeless with my ex and 4 children in 2009. Although we were still in the US, we were in Texas (which can be like a foreign country to some). Not sure what your situation is/was, but ours was black mold in my condo that forced our move. I have been there, and I know how scary it is.
I second the poster that suggested local churches. Even if you're not religious, there's help to be found there. My friend/co-worker got us hooked up with her church and they paid for our first 6 weeks in an extended stay America hotel room (not easy with a pre-teen boy and 3 toddlers, but it was a roof), which got us somewhere to stay. I paid the rent there afterwards until my ex and the two boys moved back to CA with her family and I found a shelter program for single mothers and their children. 3 months there and I reunified with my father in Colorado and ended up moving back here almost a year ago and things have done a total 360 for us.
I'm not a religious person, but found (for me) that prayer was very helpful, as was journaling and blogging. I was also in school at the time. I worked 40 hours a week and took 9 units at our local community college. It was hard, but I did it.
I sure hope it works out for you!!
