What is a period of deep sorrow that a person might feel after the death of a friend or a loved one.

Bereavement (grief). Bereavement is the state of loss when someone close to you has died. The death of someone you love is one of the greatest sorrows that can occur. Feelings of bereavement can also accompany other losses, such as the decline of your health or the health of someone you care about, or the end of an important relationship.
