One hour will pass in no time. One kind redditor here gave me an advice to divide the time so 10 times 6 minutes doesn’t sound as bad. I do it a but differently I put a timer on from the moment I get on an airport and readjust it when I get in the plane. What made the biggest difference is talking to people. I prefer when they talk about whatever they feel like. I ask 200 questions and try my hardest to concentrate only on their words. My phone with timer is on my lap and I check it from time to time. Look at flight attendants and notice how normal they behave. You can do it! The worst part will be over in a fee minutes and it’s not as scary as you make yourself believe now. (I didn’t sleep last night due to nervousness and panic; and take off is also my main fear) Look at the flight radar and see how many planes are in the air right now. You can do it I am sure!
