Rough flight from Delhi to Bangalore

The flight from Delhi to Bangalore this Monday was the most rough flight I ever took. Right from Delhi where it was raining heavily till Banglore the plane was shaking all the time. The pilot switched off the Seat belt sign off for hardly few mintues duing the 2 and half hour flight. I was so glad to reach Bangalore in one piece:)I must have travelled hundred time by now, but I dont know why I am still scared when the plane takes off.
