There are several articles that his wife has been ill with classic signs of depression. Sleeping an entire day, etc. can’t digest food. Like she’s physically fallen apart with a “mysterious illness.” Chronic fatigue often has an emotional source. Check Google for it. I’m not good at offering links. He hasn’t mentioned his wife in a long time. It’s not hard to imagine that living with Rush would be no picnic.
That’s horrible (yes, I know what chronic fatigue is). I hope those stories aren’t true, for her and for Rush’s sake... :-(
