Zoo,
can you contact Catholic Charities or some cooperative ministry or similar organization? There are programs that can help you get through problems with utility bills or rent, at least it could give you some breathing space. Their services are offered to anyone in need. And if you belong to a church, have you told yr pastor that you are needing help?
also... if yr husband is legally obliged to pay child support, and isn't paying it, he can be made to do so.
