Everyone has there own fears and anxieties , yours happens to be driving. I had a friend once who out of the blue developed a fear of driving on the interstate highway system. Why? Not because of high speed traffic, but fear that one of the long bridges would fall as she drove over it. She was in her 40's when that developed and it took her an easy five years of driving more and more extra miles on far less safe two lane highways to avoid interstates before she finally got tired of being a slave to her emotions and forced herself to use the highways again. It took a little while but she did eventually figure out how much easier life was without that fear and overcame it.
I'm not saying you should overcome it or even that you should try. I just saying that sometimes these things can be overcome and a whole new world opens up to those that were able to make it happen. When you think about it the fear of flying is the same type of anxiety. I've had many fears in my lifetime, flying does cause me a bit of angst due to having a WWII airplane mechanic for a father. One who couldn't be forced on a plane at gunpoint, because he "knew what could go wrong with them". However, I have flown all over the globe and even though boarding I feel anxious, once airborne I don't even think about it again, I just enjoy the adventure. I was lucky that my first flight was a nighttime one that approached Portugal just at sunrise. We were over a mass of clouds and every one was snow white and the rising sun caused the tops of them to have this beautiful golden border. I had never seen anything so fantastic in my life and haven't been lucky enough in the past 50+ years to time it just right to see that again. Am I a better person for having seen that? Probably not, but it is a memory that is still vivid in my mind a half a century later. If I hadn't decided to face the fear, that is a memory I never would have had.
) to and from the airport, and you just simply detached the car seat from the stroller chassis...such a cool thing...!!!
