A friend was in the same situation as you, with the difference that he always in his life had fear of flying (and he moved abroad so he couldn't visit family or go on holiday without spending half the time on the road!!). He went to a training course that British Airways runs in the UK: https://www.britishairways.com/en-gb/information/travel-assi... and since then he's even flown across the Atlantic a number of times.
I'm guessing you're not in the UK, so probably flying across the Atlantic to go on this course would sound as a sick joke, however you might want to check if in the US there's anything similar ran by other companies (or even BA!).
For me the fear comes and goes. At some points flying feels like catching the bus. At other times I am 100% confident I won't make it to the other side! so I don't think it is rare to be scared of flying even if you fly often (I do). In my case there's also the problem that I fly a lot with my family, so I'm also scared for them.
