Grieving is the outward expression of your loss. Your grief is likely to be expressed physically, emotionally, and psychologically. For instance, crying is a physical expression, while depression is a psychological expression. It is very important to allow yourself to express these feelings. Often, death is a subject that is avoided, ignored or denied. At first it may seem helpful to separate yourself from the pain, but you cannot avoid grieving forever. Someday those feelings will need to be resolved or they may cause physical or emotional illness.
