Lost the will to win?
I don't think Casey is faking it at all.
There have certianly been periods in my life where I've felt like I've had CFS and its hard to get out of bed in the morning, hard to go to the gym to do my daily exercise, etc., it requires MUCH more motivation than normal to get things done. Thankfully, I had enough in me to get everything except the exercise done.
BUT I do think if the mind is strong enough it can overcome anything - I think that Stoner has a strong mind - he wouldn't have been able 2 do as well as he has so far if he didn't, and he certainly wouldn't have been able to beat Rossi the number of times he did - esp when Rossi was strong (ie. not the times when Rossi's bike DNF). However, i dont think his mind is as strong as Lorenzo - who broke his bones and still went on to race, or Rossi who despite his age and # of championships still has a burning desire to win.
I think that Stoner is up there though, 3rd only to Lorenzo and Rossi in the heart stakes - he clearly has the anger/will necessary to tame the fiery Ducati and it says something that no1 so far has been able to except him.
I don't even think one can say he has no personality because to me, his personality is one of aggression and I like him because of it. He's certainly no mannequin a la Pedrosa.
I hope that he gets better soon and finds w/eva is needed inside him, to go back to racing as Rossi I'm sure, as well as his fans, will miss him greatly.
