Hillary Johnson, Hyde Park, NY: My brother, 61, is seriously ill with hemachromatosis, a hereditary disease that has gone untreated for years because he works on contract and rarely has health insurance. He could have a heart attack or stroke at any moment, he cannot walk, and yet he can get no health care. I have suffered from a severe disabling chronic disease for 24 years and have survived only by having SSDI and Medicare, but I am very poor as a result. I was a successful magazine journalist, and author of two books, but I can do almost nothing today. My illness, named "CFS" by the Centers for Disease Control, has been shuffled aside as a psychiatric condition by federal agencies unwilling to acknowledge existing science, or conduct their own research.
