Britain's Got Talent judge Piers Morgan told GMTV that Boyle was "emotionally drained and exhausted" after being put under more pressure than any other contestant in the show.
"Nobody has had to put up with the kind of attention Susan has had, nobody could have predicted it. It has been crazy, she has gone from anonymity to being the most downloaded woman in history." Morgan went on to say that Susan was "essentially fine" and just needed to catch up on her rest.
The seemingly shy and reserved Scot soared to super-stardom after her initial appearance on the "Britain's Got Talent" received millions of views on YouTube.
The show's winners, Diversity took 24.9% of the public vote in the final, beating Boyle's 20.2% share. The contestant in third place, saxophonist Julian Smith, gained 16.4% of the vote.
