I used to be pretty petrified of flying. To the point where I would start to worry people around me.
You can go to a doctor and get some Xanax or something like I did. A couple beers at the airport lounge, Xanax, and then a Jack and Coke after the plane takes off... you will wake up in Florida drooling on yourself. The cost though is you will be messed up for a little bit... if not, just drink some liquid courage.
Its the kind of thing, the more you do it, the more you get used to it. Its such an unnatural seeming thing, humans being that high up, going at that velocity. Planes are made to be in the air though. You also have to play the odds in your head. Look at one of those current maps that show all the planes in the air at any given moment. Its a huge number and they all make it safe.
I found I have trouble reading and watching things on a plane due to anxiety, but good music on headphones with the eyes closed is good. If you like video games, I have been able to get lost in those.
Also, front of the plane typically has a bit less sway than the back. Wings arent too bad, but you may get a little more noise/vibration
Try closing the window. Especially on takeoff.
Bumps, noises, etc, look at people around you. Most of them fly a lot. They wont look phased. Puts me at ease.
