Do not lend advice to people who are not asking it. It is incredibly insensitive to say that to someone who is dealing with their own mortality. Before you make suggestions like that again I urge you to ask yourself, “Who am I to make _____ suggestion?” Just because you’ve heard of some miracle happening for someone else because coincidentally they got better by being more positive about living. The human body is so complex, and to think that that one difference changed the course of someone’s life is fallible. To think that your anecdotal evidence applies to anyone is fallible. What you have seen anecdotally does not give you the right to preach to someone with months left to live not to feel what they are feeling. Not allowing anyone to feel what they need to feel is incredibly disrespectful.
