What options do I have for getting out of a car loan?

I financed a 2001 Ford Focus for $7,000. I owe about $6,300 on it right now. I have a one year old and I'm not going to be abel to work anymore, so I'm not going to be able to afford the car loan. What options do I have? I thought of trying to sell it, but I'll never get $6,300 for it I don't think. Probably around $4-5,000 or something. Help! I need to figure something out so I can get rid of this car payment!
