Growing up, my sister had severe OCD that ranged anywhere from her having to habitually touch pictures of family members to ensure they wouldn't die to ripping her hair out of her scalp as a way of coping. It destroyed our entire family to see her so sick. While I'm happy to say she's made a lot of progress, OCD completely damaged our childhood and proved to be the scariest thing that could happen to a family. When I decided I wanted to do a horror film, the OCDemon was the perfect monster.
