I submitted early Feb and I feel the same way. I actually resubmitted once or twice to change how far we had gotten (lines of code) and new competitors that cropped up (note: more than you'd think in such a short period of time).

Oddly, what is keeping me awake isn't the application so much. I've kind of resigned myself that it would be a nice-to-have but not a requirement. What keeps me awake now is things like reducing my monthly expenses more and more so I can work less and less for the man and more and more for myself.
