Brain,
The first thing you can do is to continue to tell your story in this forum. We are not judgmental and there are people here with a wealth of experience dealing with problems similar to what you are experiencing.
While I can't solve your monetary challenge, there are people all over the world that have lost their jobs and faced the same problem you and your wife face. It may be necessary for you to move back with your parents or her parents until you secure another job. Or there may be another friend, relative or government agency that can provide you some short term shelter or monetary assistance.
Don't despair. There is help out there for both your stress related bed wetting and financial support.
Please keep us updated and know you are not alone.
