First, sorry you're in this spot. I hope you have friends/church group/family support to help you in this time.

If it were me, I'd probably have both myself and my wife take whatever 'second' jobs we could (Wal-Mart, fast food, etc.) for nights/weekend income. I'd reserve my 9-5 hours for a full-press job search.

Good luck to you. Your skills are in demand, so hopefully this won't last long.
