Amendment of support laws

I am a student, a father , and a husband and working poor because of unfair child support no government assistance and taxes. I make 9$ an hour, my child support is 264 a month, my apartment is 590, lights 120, car ins 45$ phone 91 and food 150. That's 1480-120-590-264-91-150 minus taxes......= nothing. How am I supposed to live?

I don't mind taking care of my child, but what a bout me. The mom gets my money plus government assistance, but what about me?
