The day after disappointment should have one manageable thing in it.

The morning after something falls through is oddly shapeless. Whatever you were working toward is gone, and the choice is often between an empty day that lets everything replay and an ambitious plan that will fail and confirm the mood. A single small task is enough to give the day an edge to hold on to.

If you are in one of those days, pick something modest and finishable: a walk, a meal made properly, one errand. Let that be the whole ambition, and leave the larger questions for a week when you have more to bring to them.
