I was once stuck on Miss. River bridge in thunderstorm and it was swaying. Very scary. For years after I had fear of bridges but eventually overcame it. Another irrational fear I have is left exits off the freeway. No idea where it came from...lol.
Exposure to what one fears is best medicine...at least in my experience.
Don't worry. Fear of doing anything involving moving towards the left is common among Freepers and is a healthy survival instinct
