THIS. I used to be a very nervous flyer (basically refused to fly). Easing into it helped me a lot.

Since then I've traveled the world and am close to earning my private pilot license. I know your fear is probably emotional rather than logic based, or at least mine was, but know that your airliner can handle way more than anything that will be thrown at it in terms of turbulence.

Also the Ipad with your favorite movies / TV shows is a great idea, if nothing else because it's a long flight and you will get bored.
