Do you think maybe the action of asking others to validate your lack of apprehension could be your subconscious' way of questioning whether or not you are prepared?
Our minds are funny things.
I know sometimes I am "full steam ahead" and other times my subconscious starts barking at me to slow down.
Hormonal shifts often play into these things as well.
I'm in no means trying to have you second guess yourself, but instead just help you be aware that there will be many peaks and valleys ahead.
Enjoy the ride.
