I bet you were knocked unconcious. I had that happen to me, I couldn't figure out what was going on and was all confused and didn't come to a stop for about a block after being rearended. I figured out later that day that I had been knocked out for a bit. As for the whiplash, I feel for you, its one of the worst pains I have ever had. It lasted a long time, too. I had to go to the chiropractor 2-3 times a week for months. I also suggest going to the massage therapist, the insurance should pay for it, too, it would have helped me a lot. I hope it all gets figured out and that you can find some way to help out Hannah, too.
