Somebody pretending to sell a 2006 infinity G35 awd for 2009

Iam so devastated. I am a simple housewife that was looking for a car to buy when this man post this car as if I was buying it from E-bay. I still cant believe that i believe him. He had me send the money by western union and I did. Later He told me that he was not told that he needed to pay extra charges to send the car overseas ( because he told me the car was in Madrid, Spain) and because it sound it kind of fishy I called E-bay and thats when I found out that somebody had scam me. i dont know what to do or what to think. I am fustrated and ashame.
