Dealing with last minute publisher requests

It seems I spoke too soon when I said I was done with editing White Rose of Avalon. After sending the finished ms into the publisher I was told that they do not publish novellas. What? I was freaking out because it had been accepted for publishing. Anyway, it was a misunderstanding of some sort so I had to add at least 20,000 words to my 'finished' ms. Once I calmed down and gave it some thought, it was pretty easy to do. For the last two weeks that was all I worked on because I wanted to get it back to the publisher so we could stay on schedule for the release date. I ended up adding 25,000 words. The story was good before, but it is even better now with added depth to the plot. I am very pleased with how the story has turned out and glad that the publisher made this request.

Having to expand my ms in a short time period was a great learning experience for me. I am sure this is not the last time that a publisher will make a request like that and I am more prepared for it now. How do other writers deal with these last minute requests?

I was literally working every second I could to get the story done. I even kept a pen and notebook near my bed because ideas and pieces of dialog would come to me in the middle of the night. I would also be writing things down as I was making dinner or even watching t.v. Thoughts would come out of nowhere. These characters were inside my head the whole time. Is that crazy? It was exhausting. That is what happens when I am deep into my work. Now I can take a moment to relax before diving into a new story that I had begun prior to all this.

Now another set of characters will live in my head for a while. This is so much fun.
