Some people seem really invested, for lack of a better word, in their ailments. I don't mean that as a total insult or anything. You will find lots of people like this. My boyfriend is like this, even though he's healthier than many people 30 years younger, he's almost always worried he's about to die from some horrible disease or that he's ready to drop dead from old age. His mother is similar, all her phone calls with him are lengthy discussions of health problems. Knowing my boyfriend for so many years, I just don't think he can think of himself as anything other than sick, in pain, barely able to hold on to life. And then in the next breath he'll be all puffed up about his physical prowess and how much stronger and healthier he is than others. Makes no sense. It totally IS all in the head. I wish I could give him whatever placebo you have found. But unless it's prescribed by a doctor, he won't take it.
