This is why I suggested you consult an attorney. It's possible that you could get enough in child support and alimony to make it possible for you to stay. Or you may be able to file and get an order for temporary support that keeps the bills paid for now.
At least talk to an attorney and find out where you stand. Sometimes it's not quite as bad as you think (and WASs are often shocked to find out how much they'll have to pay).
