Yep, don't feel badly. Other than the 2wks notice, you don't owe your current employer anything. Still, I would do what you can not to burn any bridges on your way out.

I see it has been near a week since you posted about this and I am sure I am not alone in being eager to learn how things have gone. We hope for the best for you.

I want to point out though that just applying is a battle won.
