What a horrible feeling.
You
can get through this, though! Absolutely!
I agree with the don't quit your job sentiment.
In my area, sometimes people will put their house up for sale, and move themselves out, but allow someone else to stay there and rent while the house is for sale. It provides them the income to pay the mortgage on the house they're selling, in addition to the mortgage or rent for wherever they moved, while they continue to try and sell the house.
It would be a short term solution, but with the housing market the way it is, it might provide enough time for you to find something better until the end of the school year?
