Take it easy man. The topic title can be less furious than this.
I was the one that loves my car very much and that, of course, comes with the perfectionism in car paint detailings at the extreme level. I spend more than $50,000 baht every year for washing and waxing my car wherever it is done best. But, as time goes by, you will realize that it is indeed just a physical object, it's not a part of your body. So, it can be repaired and it doesn't even get pain. Putting your mind totally on it will only cause you to feel even worse. The baddy who did this to you is gone and, perhaps, already forgot what he has done to your beloved car. Generally speaking, being frustrated does not help.
Five years ago, my car was once scratched all the way through one side of the car, from the back up right to the front. That totally changes my thought. Now, I still pay as much with my car even though I'm in US and my car is in Thailand. But I did learn how to make myself happy with my car with the money I have spent, rather than let anybody ripped it away.
Sorry that I have to type in English. I'm using the common computer at the university and hence no Thai Keyboard provided.
