You have officially been attacked by the plot bunnies of long novel-length stories - rejoice! (Well, I'm rejoicing!! *g*)

I guess you could post a shortened one to the Big Bang if you don't have time to write in all the scenes you have envisioned, and then publish a longer improved version on your LJ? Not perfect, but it's one way of doing it.

Or else, you could put your life on hold and get the important thing done ... writing the story!!
