Needs & feelings dealing with sudden or violent loss are different:

Coping with sudden loss is differet than the anticipated loss of a loved one. Although it is no easier to deal with the inevitable loss of a loved one, there is time to prepare for a loved one’s passing. Thereis time to say goodbye, make plans, resolve issues, and have closure. The sudden loss of a loved one that happens unexpectedly – such as a fatal accident, murder, or heart attack – can leave survivors feeling shocked and confused. Loved ones are often left with many questions, unresolved issues, and a range of emotions and feelings, including anger, disbelief, horror, isolation, guilt, and pain. Support from family, friends, and clergy is vital to cope. With a sudden or violent loss such as suicide, or murder often, deep grief, isolation, and even shame can be felt, as there may be a stigma associated among friends and the community.
