Me too
I remember the same feeling, perhaps it is a good thing. You don't want to ever truly believe you are totally in control; 'cos you are not.
I can't remember how long the feeling lasted with me but it's long gone now. I would not be surprised if most pilots have felt it at some time or other. It will pass.
Mine did and and have been a com pilot for 5 years now.
Anyway, how often will you be flying on your own?!
