Keep your religious beliefs. This may be important to your relative. Keep a sense of humour. Never lose hope. Burnout may also be caused by a lack of acceptance on the familys part.
Some people are unable to recognize the illness for what it is.
Many of these people attend support group meetings on a regular basis, insisting all the while that their wife will get better, that their son will be cured. One mother said that she devoted all of her time to her son the first year he became ill. Then it was pointed out to her that because she was a social worker, she felt that she ought to be able to help him. There are those who push themselves to the limit. They never let go.
