Agree with the above. But dont beat yourself up over it. Take this as an important life lesson. Follow the WCI rule of thumb for deciding how much car you can afford and always pay cash (or pay it off in a few months). No more than 20% of your salary on a car will prevent this from happening again. That means spending up to 18k for you. You can get a very nice car for that price, but pay cash for it.
I'm not sure that's my rule of thumb, but it seems like a reasonable one. The only car one I've ever heard is Dave Ramsey's- "No more than 50% of your annual income in things with motors."
