I just re-discovered this quote in my story - I think you will like it:

A quote from In Other Worlds, by A. A. Attanasio:
Ever try to write a story? Notice how the characters get out
of hand almost at once? That's because they partake not only of our
imagination but also of our will.
Regrets and expectations. That's all I am when I'm not
writing. And when I do write, I am the thing the stories come
through. I am less than myself and my characters more than me.
My insanity is really that I don't know if I am mad or not.
Reality is an open mystery, and I've closed myself off too long with
my ideas and emotions.
