Most of my annoyance/anxiety about flying comes from things that aren't the flying itself. There's security and TSA, there's getting to the airport on time, there's the anxiety of deciding if I can get food and eat before the flight starts boarding or not (same with going to the bathroom), there's the actual boarding that is organized in a way inefficient , there's layovers and delays (or catching really close connecting flights), there's getting sick due to exposure to lots and lots of people , there's making sure I neither forget anything nor have them stolen. Those are far more annoying or anxiety inducing for me than flying since i can just sleep and listen to music at that point.
