Like you, I hate flying in turbulence, even though it doesn't prevent me from flying. I know intellectually thet there's nothing to worry about and it's a normal part of flying but emotionally it still gets me. I find it helpful to look around at my fellow passengers and at the flight attendants and note how unperturbed they are. Doing this calms me down somewhat.

Strangely, my wife loves turbulence. She enjoys a bumpy ride. Go figure.
