How can I get out of my car loan?

I purchased a car 4 months ago and financed a loan for 25,000$. I can’t really afford the gas or monthly payments. I’ve only made 4 payments on it so far and since I rolled taxes into the loan I’m upside down on a trade in. I’ve already tried and they’re only willing to give me 17,000$ for it leaving me with 8,000$ of debt. No bank was willing to give me another loan on top of that. Are there any other ways I can get out of this loan without destroying my credit?
