Well I did even worse on my QXC, involving fire engines & a temporarily closed international airport! And while it did not (quite) cause me to give up, I still feel a degree of anxiety prior to every flight.
But as has been pointed out earlier, this is actually a GOOD thing, and I don't relish the day - if it ever comes - where I don't feel something of this prior to take-off. So unless it is debilitating, I would not let it put you off.
Dkosky: 'envelopes with windows' - really? That has to be one bizzarre phobia. Care to elaborate? Come to think of it, solicitor's letters arrive in that format so perhaps I can understand ;-)
