To the OP, download an app called SOAR (on iphone, prob on Android also). It uses the built in accelerometer to tell you how many Gs the plane is currently experiencing. On a recent, midly turbulent flight, it went between 0.80 and 1.20 G in the worst chop, but mostly stayed between 0.99 and 1.01 G during the majority of flight (which isn't too different than the readings I got on my toilet at home). A plane is rated to sustain flight between -1 and 2.5 G and up to 5 G temporarily.
It also has some good mental exercises to help you calm your anxiety.
I have flown 90 segments so far this year and I still get jumpy/white knuckled at turbulence and the app has helped me.
