Do you mean as an illness description, or as a symptom description? Because as an illness description, yes, fully agreed, I think we're all aware that "chronic fatigue" as a diagnosis is like "chronic headache", just a description of an ongoing symptom, and not remotely the same as ME or CFS. But the actual symptom of chronic fatigue is a key part of having ME/CFS, so in that sense, yes, of course I would describe myself as having chronic fatigue, just as I would describe myself as having chronic pain and chronic GI problems. I've seen a few people saying things like, "ME is not about fatigue," or, "fatigue isn't the problem when you have ME," and I have always been utterly confused by them. Fatigue alone isn't the problem, absolutely, but it's the primary symptom, so how can you have ME without fatigue?
