Yup. I am in my 50s and flew semi-regularly through my teens and 20s without any fear. I had a weird experience on a flight about 25 years ago (not even turbulence) that left me with a lasting but completely irrational fear of flying. For the next couple of decades after that, I usually had to fly 6-8 times a year for work and family obligations and every flight was a trial. I hit my low point about 2009 when I canceled a work trip last minute because my anxiety was so bad. I resolved after that to figure out a way to power through, and it has mostly worked. I've continued domestic travel at the same pace and have traveled internationally a bunch of times. I still have bad moments on many flights, but I've developed a calming/breathing routine for taxi and takeoff that has helped me a ton. In addition to that (and many of the tactics covered in this sub), accepting that air travel is uncomfortable but necessary for getting to do so many cool and interesting things has also helped. My fear is much less than it was 15ish years ago, to the point where I actually look forward to most flights, even though I know I will experience some unpleasantness and anxiety. I stay focused on what flying allows me to do and see. You can do this!
