If it were possible to heal sorrow by weeping and to raise the dead with tears, gold were less prized than grief.

Tears do not buy anything back. If grief could purchase a return, people would hoard it more carefully than gold, and no one would ever weep in vain. Since it cannot, crying is not a transaction, and its worth was never in what it repaired.

That may be a relief rather than a loss. You are not failing at grief when it changes nothing outside you, and there was never a quantity of it that would have been enough. Let it do the smaller thing it actually does, which is to let some of the pressure out, and let that be sufficient for now.
