The reason that I started writing was to give my demons a place to play other than in my head. I gave them new worlds, new friends, and landscapes where they could be themselves. Since then, I have been relatively demon-free in my thoughts. They are happy and I am happy. It's a win-win!
Before I started writing, I had trouble with insomnia. It would take a minimum of three hours to fall asleep once the light was off. Some nights, I wouldn't sleep a wink. So I started telling myself stories in my head to pass the time. Those stories and characters became strong and insistent. They wouldn't give me peace until I wrote down their dialogue and plots. I would stay awake all night to get these stories out, sometimes not sleeping at all and then getting dressed to go to work all day. Honestly, it wasn't all that different than before because I hadn't been sleeping anyway.
Once that first book was finished and out of my head ... there was peace, and sleep. I still have to tell myself stories to fall asleep each night, but I'm only up for about an hour after lights-out nowadays. I also have less bouts of depression. Less feelings of inadequacy. I'm in charge of my demons and they know who's boss. I give them an outlet and they leave me alone.
Writing has saved my life, made me a better person, and given me joy. I couldn't be more grateful.
