it's a scary feeling, one that's tough to get rid of. I was just in a bad car crash four months ago. some distracted idiot rear-ended me going 60mph when I was stopped (claims he never saw me)! I had/have lots of injuries, head to toe. I was driving again a few days later, but the fear is still there. For me, there is no logic to this car crash accident that I can rap my head around - the weather was fine and roads were dry - just can't figure out why it happened. So even now, the fear I feel when a car is behind me is almost overwhelming at times, like my heart stops! I almost freak out, hoping and praying that they see me. I've even pulled off into a right-hand turn lane, just so the vehicle could go around me instead of following me. I have no idea if I will ever get over this fear... (and I've been driving for almost seventeen years now)
