"can't stop" is drawn by the inspiration of the idea of self-destruction. sometimes, we do things that would destroy us and affect us negatively without knowing that. Then, once we realize that, it becomes very hard to stop it. it becomes like cigarettes' addiction. we become close to this addiction that leaving it is like killing that part of yourself that taught you how to survive. you can't stop doing that thing that kills you soul slowly, steals your happiness, and destroy every part of you.
