R.,
I don't understand why you haven't been able to get public assistance. If you are truly needy - it should be there for you.
At some point Catholic Charities and other organizations will only help so much, then you need to be able to do it on your own. It's not permanent help.
Go to the library. Borrow books by Dave Ramsey and Suze Orman. Even with a part time job - they show you how to manage your money.
It's October - start going to Goodwill and other places similar to that and see what you can get. Christmas isn't about buying your kids the latest and greatest. It's about celebrating the birth of Christ.
Get your children's father on-board. Where's his child support?
Why aren't you getting more from him?
Where there is a will, there is a way. Through Christ all things are possible. So if you believe in God. Have the will - God will show you the way.
Good luck
