I very recently got my license, and bumped into a car inside a car park the next day. There was no real damage to my car, but I left a definite dent in the car I bumped. There was no one around, and I just drove away. I've felt unbelievably guilty about it since. I realise that it was a completely dishonest, awful thing to do, but I didn't get the license number of the cat I hit. I realise it's no good to feel so bad after the fact but I don't know what to do.
