I'm ok with flying . . but I once sat next to a woman who was terrified. She kept latching on to my arm every time there was turbulence. She told me that she hated the turbulence because she could feel the airplane falling out of the sky every time we dropped a bit. I realized that she actually thought that when she felt that sensation, she thought the airplane was losing its grip on the air and just free falling to earth. I told her that the airplane is still flying just fine, but since air currents are going up and down and all around, the airplane moves with the currents and it feels like the plane is in trouble. It's like sailing down a winding river - with the boat just following the winding current. Once she got that into her head she was able to relax.
So I don't know if that's an issue for the OP, but if so, just keep in mind that the airplane is still flying just fine when you feel turbulence.
