The best thing a person can do is look up the disease on the Internet so they are knowledgeable about the disease and thus, they will know what the person is going through and how they feel. Just being there to listen; a shoulder to cry on are a great comfort for many people with a serious disease. For those that are religious they can pray together or go to church together often finding strength. If the person who is ill can get out and be mobile then it would be a treat for them to get out of their home and back into the flow of life. Going to dinner; an uplifting movie; walks that have beautiful scenery and is a quiet place to reflect ones mind is also of some help. If the person does not have a pet such as a cat or dog this may be suggested depending on how ill the person is. Some people who have a serious illness may have hobbies such as photography. painting, etc., and with some encouragement from their friend to get back into it may help the person who is ill.
