response: I can't say but there is no cure and treatment would be symptomatic.
original_response: i wouldnt assume the worst, But currently there is no known cure, But there is promising treatment for it.
history: I'm feeling a lot more tired than I usually have been. I'm worried I might have an illness of some kind, like chronic fatigue. Did you run a diagnosis on yourself? It's based on your symptoms? What kinds of symptoms should I really be concerned about? Surely if I'm just tired I don't have to assume the worst, right?
knowledge: There is no cure, with treatment being symptomatic.
