sell my wedding band?

So...this month has been very tight with money and it's looking like we are not going to be able to afford our utilities or buy food for 2 weeks. I'm thinking of selling my wedding ring. I'd love to replace it with a tiny ring and use the $$ for food, bills. Makes me sad but also it is much sadder to think our gas may be turned off this weekend and my family won't have much food . Anyone had to do this?
