Most of the time when I'm in the air, yes - I'm quite relaxed. Or, perhaps I should say "not anxious". However, like you I had an accident, and things haven't been quite the same since.
My accident was very sudden - everything seemed fine until we touched down, whereupon the plane flipped onto its back due to a problem with the ski-equipped landing gear. Here's a pic:
The accident was in April this year. I was a passenger, and was unhurt. But I find now that I talk myself out of landing at difficult strips when I'm on my own, and suffer some anxiety before flying if I know that the flight is going to involve "difficult" flying.
It's very irrational, because I know that I'm not going to have another accident for the same reason, but the anxiety is there all the same.
You asked if it ever goes away.... I hope so!
Perhaps we need a self-help group for traumatised pilots!
