response: Is yours biological or genetic? I guess not a lot is understood about it.
history: Hello. I have chronic fatigue syndrome, which means I'm always low on energy. Sorry to hear that. It's also known as also referred to as myalgic encephalomyelitis (ME). How severe yours, and do you suffer from long-term fatigue? Thankfully mine is not too severe, but I do suffer from long-term fatigue. Unfortunately there is no cure.
knowledge: Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood.
