+1 on sell the car. If you need a car for the occasional trip out of town, rent one. That is cheaper than car payments, and you can control when it happens. If you don't have the money to make a trip you stay home, whereas a car payment is due whether or not you have the money for it.
Pay food first, then rent and utilities, then the loans & credit cards. Prioritize it so that if money runs out, you have pre-made the decision about who doesn't get money that month or who gets less than a full payment. And call your creditors and explain the situation. You'll end up paying a fee, but you can stave off having collection agencies hounding you.
If you even just send them $10 that's better than missing a payment entirely.
