That's an excellent therapy for dealing with those feelings of hysteria. I would imagine another is to force yourself to get stuck into a favourite author's book or concentrate on a movie/TV program. People speak well of the Fear of Flying courses. But it ultimately comes down to: if you want to fly, what are you going to do about your own problem? Find your own therapeutic things, do a course, but don't necessarily expect the crew to pander to you and indulge your panic with constant PAs, which can be annoying to the vast majority. It is not being brutal, but if you hate boats leaning over and panic, don't go sailing- you'll spoil the day for others, if you hate boats rocking, don't go to sea. If you can't take turbulence that a ppl wouldn't flinch over, don't go flying.
Well done for rationalising the cause and working out a treatment and finding a partial solution that helps for you. I'm sure you will find with every flight, the problem progressively recedes.
