Is it too late to offer my advice?
To continue a story you have to have motivation. I for one keep telling myself that if I don't write something I'll never publish a book. Since I fantasize about writing a great book someday, it gives me the motivation I need to continue. Call it the X factor, Y factor or whatever, but whatever your's is about writing then just think it and it'll help. Hope that helps you.
Please no jokes about me wanting to write a book.
