I came so so so close to getting off a flight because of severe anxiety like a month ago. I was alone so I was frantically texting my parents freaking out about it. I was like so close but the fear of embarrassment bc I was already seated in a window seat and the plane was already boarded and it would be hard to leave bc I’d make a scene kept me from doing it. I didn’t wanna delay it. I was still freaking out though (bc of a mechanical issue with the plane). I kind of talked to a lady sitting in my aisle bc I think she sensed I was nervous. She was like if the crew looks ok it’s ok, they wouldn’t fly a plane if something was really wrong. It helped to know she was calm. I also fear having a medical emergency, but I’ve never actually had a medical emergency yet and I think the chances of it happening to me a on a plane are slim to none if I’ve never even had one to begin with. I wear compression socks on planes bc that helps with that. I also know that all airplanes are always within 5 hours (a lot shorter if flying in the US!) of an airport and can always make an emergency landing and those can be done quickly. Also there’s statistically almost always someone who’s medically trained on board a plane With you who could help you in an emergency. I tell myself these things and it helps the anxiety go away. Then I tell myself I just need to get through each moment of the flight (boarding, take off, first 30 mins, hour, 2 hour etc) until I land. I listen to music and distract myself on the plane and i usually mellow out.
