Show her that there are many people in this world who need what she can offer. Help her see that possibilities can still exist in her life. Talking with others who are suffering the same type of grief and loss can often help. Sometimes herbs and vitamins can be helpful in coping with nervousness, sadness, depression. Give her a comfort basket, full of items, like a stuffed animal, tea, an inspirational poem book, something that mirrors her spiritual beliefs.
Hugs help too.
Holding a person's hand lets them know you are right here. Once, when I was feeling very depressed, a friend said little to me, but instead proceeded to give me a wonderful head massage. Touch is important. Give her the gift of a one hour massage. Give her a chance to be nurtured.
