Why can't I stop, even when I'm running on empty?

You are tired. Not the kind sleep fixes. This tired sits in your chest before the day starts. And still you get up. You answer the message. You finish the task. You show up again. Not because it works. Because stopping feels like failing, and you have never let yourself fail. Here is what you have not asked: what if the motion is the problem? You call it discipline. It may be fear wearing discipline's coat. A wheel can spin all day and go nowhere. You have mistaken speed for direction. No one gave you permission to stop. So give it to yourself. Not forever — one hour, one task, one honest breath. See what is still standing when you do. And if this tiredness does not lift no matter what you stop doing, say that out loud to someone outside your own head — a doctor, a friend, someone who can help you carry it.
