I HATE any kind of fairground rides (even the kiddie ones) and would NEVER EVER consider a bungee or a parachute jump. So I am a properly qualfied scaredy-cat/wimp, .... and yet I rather enjoy flying!
I have flown a LOT now over the years, on all kinds of planes and short/long haul. I have experienced (minor) turbulence and an engine failure after take-off/return to airport but I wasn't really perturbed. I felt safe at all times.
It's boats which terrify ME! (That recent sinking in South Korea ... or the one off Italin coats ... that's what I am thinking most of the time I am on any kind of boat.) But I still go on them ... prefering a big one if I have to go.
With planes, I just have COMPLETE FAITH that a commercial pilot and all the safety checks they do before they fly will mean it'll be fine. (Cos it's really bad for business if they crash so I know they take safety very seriously!)
I have less faith in a lot of car/bus drivers to be honest .... who can kill you if they are drunk or if they are tired/bad drivers/have make a small mistake.
YANBU to fear flying .... as it's quite a common phobia and I do understand that it's an irrational fear. And a BIG problem to solve.
But YABU not to try to get around your fear, because if you DID, you could go to the US (which you said you'd love to visit) & your DH would be SO proud of you & pleased you could now go abroad with him.
So please try to see if you can get some help? (As I am sure it is quite CURABLE!)
As mentioned, there are special courses run at airport for (all the) people who hate flying. Also there's hypnotherapy maybe?
Really hope you manage to face this and conquer it. And do come back and let us know when you have!
Lots of luck OP!
