On days when nothing feels solid, a routine is the rope you can still hold.

When everything is uncertain, decisions get expensive, and a routine removes the need to make them. The shower, the walk, the same breakfast, the same hour for homework. None of it fixes the underlying thing, and that is not its job. Its job is to give the day a shape while the rest of it stays unclear.

Pick three fixed points and protect them even on the days you cannot manage much else. Keep them small enough to be possible when you feel terrible. Finishing those three on a bad week is a real result.
