In order to deal with fear of flying effectively you acknowledge to yourself that it is not just a matter of your 'nerves', of developing determination or will- power, or of 'pulling yourself together'.
Fear of flying is a phobia.
It may be a quite mild phobia or a severe one. But it is a phobia . A phobia is an irrational fear To be precise, it is a mainly irrational fear. Because most phobias do have a degree of realism. And fear of flying is a partly rational and partly irrational fear.
