Hey Alex,
I am in the same position as you except I have been in the workforce for some years and have an established career, which I am giving up to become a commercial pilot.
The recent woes of the airline industry have only made me more determined to be at the top of my game, and be the stand out trainee of the bunch. If new pilot positions become rare, I want to be there with the top performers!
Believe in yourself mate, and follow your dream.
Good luck with it.
