Your child is starting to talk about “bad thoughts.” They worry they might hurt someone. They worry they might hurt themselves. This behavior is out of the blue. They promise they don’t want to kill themselves, but they worry it will happen anyway. They don’t want to jump in front of a car, but what if they do? They don’t want to stab you, but what if they do? The questions don’t stop there. What if something they do winds up killing those they love? What if they don’t wash well enough, pick up good enough, do things carefully enough. Would that put others at risk? Welcome to the world of Harm OCD. The one OCD theme that has parents running to professionals more than any other OCD theme.
