Help!

I am a divorced school teacher. The DOE began garnishing my wages 6 months ago for 15%. This is putting me into a severe hardship to pay my living expenses (I have no credit cards,etc.). I have to pay $1150 a month in child support to my ex-husband. I am a recovering alcoholic that destroyed my marriage, family, credit, and almost my career. On paper it looks like I make ok money per month, but with the child support, children's health insurance, and now this garnishment...I am literally eating cereal for dinner every night.

Is there anything I can do?
