Encourage the postponement of major decisions . Whatever can wait should wait until after the period of intense grief. In time, gently draw the mourner into quiet outside activity . He may lack the initiative to go out on his own. When the mourner returns to social activity, treat him or her as a normal person .
Simple understanding is enough.
Acknowledge the loss, the change in the mourner's life, but don't dwell on it. Be aware of needed progress through grief. If the mourner seems unable to resolve anger or guilt, for example, you might suggest a consultation with a clergyman or other trained counselor. Especially if the bereavement is devastating and you are close to the bereaved, you may have to give more time, more care, more of yourself than you imagined. And you will have to perceive the special needs of your friend and creatively attempt to meet those needs.
