Well I'm afraid medical professionals frequently get on with their stuff without explaining exactly what they're doing, like filling a giant syringe without saying where they're going to put it. I think you have to accept you are an extremely nervous passenger overafraid of the slightest noise or movement. Now should the pilot cater for the most nervous passenger on every flight, even if there isn't a bundle of nerves on most flights he carries, and make a pain of himself telling everyone 'not to worry' every 2 minutes, or can he expect people who do have a severe problem of nervousness in the air to be a little proactive in getting treatment for their condition and actually trying to do something about it? Bear in mind that some flights can have 400 people on board, many sleeping, who don't want to listen all flight to nervous people being constantly told 'it's OK!'.
Either fly and accept it and control your nervousness or go by train/boat, but please don't go flinging insults so lightly.
