If we feel grief-struck on losing a loved one, how do we relate with Krishna thereafter?

From Tamil Mani P

Supposing a loved one dies early as a result of a disease or some unnatural causes, how can we remain equipoised, when even Krishna’s greatest disciple, Arjuna, mourned the death of his son? How do we compensate (or relate to Krishna) for having shown our feelings of distress at the death of a loved one?
