Prolonged grief is a condition in which a person feels great anxiety, loneliness, and intense longing after the death of a loved one. It is sometimes also called complicated grief. The symptoms last a long time and can take much of a person's focus and energy.

A person with prolonged grief feels anxiety related directly to the loss of a loved one. This condition differs from post-traumatic stress disorder (PTSD), a condition in which a person is anxious and fearful that traumatic events will occur again.

Prolonged grief can be treated by a doctor and a grief counselor.
