Just as there are Journals of Negative results [1][2] so too should there be a journal of failed startups. Your detailing of what caused the failures could save thousands of man hours and potentially someone falling into the same traps.
Goal #1 for you right now is to get your family in order and steel the troops for tough times ahead as you get back on your feet.
In short order though you should start simply documenting the process that led to your company failing. Not only will you learn from it but it will help others.
If you are in the DC area don't hesitate to reach out to myself and my family. We have kiddos the same ages as yours so they would have a ball.
