The grieving process usually takes at least one year in order to experience all the “firsts”. The grief process may take as long as two or three years, but the intensity of the emotional pain should decrease during that period of time. It is important not to make important decisions too quickly because you will feel differently about things as you move through the grief process.
A sudden or unexpected death may cause significant initial shock or numbness and may also lengthen the grieving process.
Knowing in some way that a person is going to die (anticipating the death) does not reduce the intensity of the grief or pain. Anticipating the death may help motivate you to engage in some planning (e.g., concerning financial, funeral, and relationships matters) which might make the grief process less cumbersome.
The grieving process is also affected by many other factors, including the personalities of the people involved, the type of relationship someone had with the deceased, and the present circumstances of one s life (e.g., age, family structures, finances, health, employment, children, etc.).
