Grief helps address the loss

Because grief is distressing, it motivates us to learn how to live in light of the loss. 

Our relationships cannot continue the same way as before. Grief offers us an abundance of information about how to change the relationship. For example, widows and widowers often must decide whether to continue to live in the same willing they had shared with their spouse, which belongings to retain or give away, and which charities should receive the deceased's assets.
