Respect a family member's need for privacy and private grief. Strenuous exercise alternated with relaxation will help alleviate physical reactions. Remember that you're experiencing normal reactions to an abnormal situation. Talk to people. Talk is healing medicine.
People do care.
Give yourself permission to feel rotten. You're suffering from loss. And, it's all right to grieve for the loss of material things. You wouldn't have obtained them or kept them around if they didn't have some meaning to you. When you're feeling rotten, remember that those around you are also under stress.
