OOOOOOH. I hate it when that happens. Thats a sinking feeling isn't it. It's really a small thing. We had them all the time in the parking lot of the Supermarket where I worked. It will be alright. Some people instead of hitting the breaks,hit the accelerator. Only a few did that. You didn't do it on purpose. It was a mistake. No ones perfect. You had sleeping problems on top of that,so you where tired. Try to give yourself some slack. Brokenfriend
