I can relate to your anxiety while flying. I was a white-knuckle flyer for about 20 years after witnessing the aftermath of a jetliner crash in San Diego in what was at the time the worst airline disaster in U.S. history. But then one day, I became exhausted from all the pre-flight and in-flight anxiety and decided to let my fear go. It worked for me, but your mileage may vary. Good luck and safe travels.
