Denied for food stamps

I have a question. I cannot work, and I stay home with our kids. My husband makes about $4000/month, we were told we don't qualify. However, his travel and gas reimbursement goes onto his paycheck and that's over $2000/month so In reality we make about $1800. We tried to explain it to them and his paychecks even show travel and gas reimbursement on it but they said there's nothing they can do?

We were on it about 2 years ago and we were making about the same and we got it. Now we have more mouths to feed, making the same, with more bills, and we don't qualify? What can we do?

We are drowning in medical bills, even with insurance. Plus college, rent, food, kids, all that. I am considering dropping school and getting a job, even though I'm in no condition to work.
