Get over my fear of airplanes

I want to travel to so many places in my lifetime, but I’m too scared to fly in an airplane. The last time I was on a plane was a little over a year ago, and it wasn’t so bad. I thought I was getting over the fear then, but now I don’t think so. I’m not planning any trips yet, but when I think about flying, I get this awful feeling in the pit of my stomach.
