From your description, it sounds like this event made a sudden change in how you feel about it. It was a fear that sprouted up immediately after a definite source. You had an earnest fear that you were about to die because you didn't know turbulence like that. That sounds like some kind of mild case of PTSD to me. It's not always super-dramatic shell shock or trauma from war; any fearful event can give you some level of post-traumatic stress. When I was twenty I was run over by a van running a red light and dragged along the road a good way. I was fine, but after that I had a very hard time crossing the street without getting jumpy and having my hair stand on end. If somebody edged out into the intersection to turn left instead of waiting behind the line, it made me freak out and run across or even turn back. It was an extremely physical sensation, like I was losing control of my body with fear. It looked really silly to other people, and I was kind of embarrassed. I'm fine now. Even going to Southeast Asia and crossing the chaotic roads there which have no signals isn't frightening, where people must steadily walk through a mass of still-moving traffic. I think it was a case of exposure. I had to keep going out there and exposing myself to something I was afraid of. I lived in New York back then, so I was obviously exposed to it countless times every day as a matter of course. Flying might be different because it just happens so much more infrequently. In any case, I'm not a professional; I hope you'll excuse my amateurish diagnosis and personal anecdotes. I'd recommend talking to somebody with training about your situation and seeing what they think. Don't be embarrassed because this isn't the kind of harrowing event typically associated with post-traumatic stress. It can happen at a lower intensity with everyday fears too.
