"Grief is the normal response of sorrow, emotion, and confusion that comes from losing someone or something important to you. It is a natural part of life. Grief is a typical reaction to death, divorce, job loss, economic uncertainty, a move away from family and friends, or loss of good health due to illness. Grief can be a normal reaction to the environmental, cultural, and economic losses due to the oil spill disaster in the Gulf Coast."
