"mental turbulence that overshadows your achievements." Congrats my dear. You don't deserve it any less than the rest of us, and you'll discover that imposter syndrome will try to rear its' ugly head, no matter how much more experience you come to acquire. That's the sign of a true writer - we're never quite good enough to ourselves. That's truly some crazy mental turbulence, but just keep writing and enjoy the bumpy ride friend :-)
