Answer:
No, you cannot die from CFS. IT can cause depression and is very dificult to deal with but is not deadly.
The problem is properly diagnosing the cause of CFS. According to the book 'America's Biggest Cover-Up: 50 More Things Everyone Should Know About The Chronic Fatigue Syndrome Epidemic And Its Link To AIDS', in 1993, a leading CFS researcher, Dr Paul Cheney reported that five of his twenty CFS patients died in that year- two committed suicide and three, like AIDS patients, succumbed to overwhelming infections that their damaged immune systems just couldn't fight off.
There is much speculation that CFS patients may have similar immune system deficiencies as so-termed 'non-HIV AIDS' cases.
