How can strong advice be given to a 17-year-old orphan who has lost his parents and lives alone, to help him feel better?

The young man is advised to be patient and seek reward for the loss of his parents, for whoever perseveres, Allah will grant him patience and aid him. Among the things that help one be patient is the servant's knowledge that this world is finite and merely a transient abode. He is also advised to frequently remember Allah, obey Him, maintain his prayers, and avoid sins, as this is among the causes for healing from psychological ailments. He is reminded of the great reward for those whose affliction is great, and that trials expiate sins, and that all affairs of a believer are good. Finally, he is advised to avoid isolation and seek good companionship.
