A) "We think the disorder is caused by trauma or abuse early in life.You seem very concerned about your wife;we could talk about your concerns if you like."
B) "I doubt there is anything you could have done that made it worse or could do to make it better,because we think it is primarily a genetic disorder you are born with."
C) "These disorders arise from within the person;they are just something the rest of us have to be supportive about until they get better on their own."
D) "These conditions are understandably frustrating;it's hard to imagine why a person would put their loved ones through what they do."
