Coincidence
Sometimes when learning to fly, and indeed flying, you will feel scared and uncomfortable.
Unfortunately it just goes with the territory.
Although the fear of turbelence will go over time there will be other things that make you feel uneasy. It's just part of "hobby"
don't forget, if you are diving then you shouldn't fly for 12hours if you dived less than 30ft, and you shouldn't fly for 24 hours if you were deeper than 30ft.
