if you have a fear of flying, before seeking treatment you might want to ask yourself several questions:
1.
What exactly were the circumstances of the flight on which the fear of flying symptoms first appeared? 
Why were you flying?
What happened just before the flight?
What happened during the flight?
What happened just after the flight?
(Try to recall the facts as well as the exact words of anything that was said.)
2.
What was happening in your life before the fear of flying symptoms developed?
Did you experience any major life changes before the fear of flying symptoms developed?
Did anything happen that left you feeling uncertain or conflicted before the fear of flying symptoms developed?
Had anyone done anything to you that had left you feeling emotionally hurt and angry before the fear of flying symptoms developed?
3.
What exactly might a fear of flying prevent you from doing?
How do you really feel about not doing it?
Maybe you don’t really want to do it.
Or maybe you feel guilty about doing it.
Who knows? You might end up in treatment for something other than fear of flying, or you might be able to solve the problem yourself without professional help.
