Hi D. -
That's a very sad situation. There is a book called "Reaching Out To Those Who Grieve" by Katie Maxwell. You can find the info online too. But basically, it says that the things you can do to help are:
1) Listen - with your eyes, ears and heart
2) Touch - a hug, pat on the arm or around shoulder, lingering handshake
3) Respect the initial phase of survivor's denial
4) Provide food - disposable containers, label with cooking or freezing directions and your name. Or bring groceries.
5) Send a card with a handwritten note
6) Continue to call on a regular basis
7) Validate the loss of those who grieve, including grandparents, children and fathers - remember the forgotten grievers.
8) Attend to practical matters - transportation for out-of-town visitors, house-sit, baby-sit, offer to make phone calls, clean house, do the laundry, run errands, help dress children for funeral, help address thank you notes, service care, stay with relative who is unable to attend funeral, sit with children at funeral, etc.
9) Ask other family memebers what needs to be done
10)Accompany survivor to funeral home and support them while they make choices
Mistakes to avoid:
1) doing nothing
2) Avoiding mourner
3) Failing to attend funeral
4) Changing subject when survivor wants to talk about deceased
5) Refraining from using the deceased's name
6) Using platitudes (It must be God's will, He's better off, God must have needed another angel, Now he won't suffer anymore, Time heals all wounds, She's led a full life, You're strong, It could have been worse, God has a plan, etc.)
7) Saying I KNOW how you feel
8) Trying to "cheer" people out of their sorrow
9) Giving advice
10) Failing to offer continued support (calls, visits, invitations)
11) Being afraid of silence
12) Feeling we must do something to "fix" the problem
13) Being afraid to show emotions
14) Asking innapropriate questions (Do you plan to remarry?, How did your husband become ill?, How did the accident happen?, What are you going to do with her clothes?)
15) Judging people's level of grief
16) Defending God to the angry bereaved
17) Taking the survivor's anger or resentment personally
18) Not allowing the bereaved to express the feeling of guilt
19) Suggesting pill or alcohol to calm the bereaved
20) Doing too much, not allowing the suvivor to be alone
21) Using euphemisms (She went to sleep, she went home to meet her maker, he passed away)
22) Promising more than you can deliver - be careful when making a committment not to promise the "moon and stars", when reality sets in you may not be able to fulfill those committments
23) Sharing confidential conversations
24) Questioning the suvivor's decisions. Give opinions when asked with the understanding that it is just your opinion
25) Getting involved in family dynamics
26) Telling the survivor to be brave and strong
27) Waiting for the survivor to call you
28) Playing matchmaker
Hope that helps... good luck, L.
