You will find that actually flying isn't the problem and won't bother you a bit.
It's all the people in the rat race getting through security, rude TSA agents, the idiot trying to cram a full size suitcase into the overhead compartment, the squalling kid in the seat behind you whose parents don't believe in discipline, the guy who had way to many drinks before he boarded, the sick person beside you that sneezes and coughs the whole trip, being crammed against the window or getting hit in the shoulder by every person walking down the isle to use the bathroom, and finally jockeying for position to grab your luggage at the baggage claim with the constant fear that you will never see your bag come out of the chute.
Flying is fine. Putting up with all the other crap is horrible. There have been times that my flight has hit turbulence and the thought of crashing crosses my mind, but it doesn't bother me much because I realize that if the plane crashes, my misery will be over sooner than expected which isn't that bad of a thing.
