Yeah man, I've taken quite a bit of plane rides in my life. There actually is greater chance of getting into a car accident than a plane crash. Something like every 5 seconds someone is gettin into a car crash. Plane crashes? sure they happen but most happen with private planes and those small little dinky planes. Passenger planes RARELY crash.
Once you get in the air, its kinda boring. bring books and music. the only exciting parts are takeoff and landing. but even those arent very eventful.
My brother and mom are the same way, if its really that big of a fear go to the doctor and he will give you some pills to knock you out for takeoff.
Good luck, and don't be scared, if I did it when I was 10, you can certainly do it now.
