Psychology of Creative Writing

I use to write about the chase and the thrill of the excitement.
Now, I write about the psychology of the struggles of regret and tormenting secrets.
I love writing the psychology of it all. And I find it very difficult to go back to mainstream or pop art.
My stories are darker, full of secrets and have much more heart. They scare, excite and make me sick. I love it.
Maybe that was why I chose psychology and creative writing at college.
