I'm so sorry you have to go through that. My dad accidently ran over my pet toy fox terrier when I was 7 or 8 years old. Spook was by the fence on the other side of the car, he always chased the car out of the driveway, but usually on the 'open' side of the driveway. Mom called Spook to the front porch, dad stopped the car, then started backing up again because he thought Spook had made it to the porch and the poor thing hadn't. I was devasted, not to mention my dad's feelings. Mom saw the whole thing, I was in the house and ran out and saw Spook. My dad buried him in the back yard and I visited him often. Time will help you heal, words can't make you feel better, really. It just has to happen from the inside out.
