Does the reward vanish if one is distracted from his affliction or forgets it, or is it necessary to feel the suffering to attain the reward?

A person should not make themselves suffer and torment themselves, but rather ask God for well-being. It is sufficient to be patient when a calamity occurs, for they will receive a great reward. The praiseworthy patience, for which one is rewarded, is that which occurs at the surprise of a calamity, because consolation comes with the passing of days. The one who has become consoled about their affliction does not truly deserve the name of patience. Rather, the true patient one is he who restrains himself from grief. The reward is consequent upon steadfastness at the first instant that the demands of grief attack the heart. It is sufficient for the questioner to be patient at the first shock, and they are not required to renew their affliction. However, if they recall their affliction without effort and then praise God and say "To God we belong and to Him we shall return," they will be rewarded.
