I don't alway write prologues; depends on if I feel the story will need one, or if I have a good idea for the prologue. If not; I won't. I like my stories to start head on, no warning haha.
I'm sorry your inspiration has been on the downlow. It is a very annoying affliction; I know. Fitting your ideas together might need an extra brain. And with that I mean someone to bounce ideas off. Someone to brainstorm with. I find that my best story plots would never been created if I had not used someones amazing brain. (I do a lot of co-writes).
