Hilary told Stella magazine: "I go get stressed out and I do get sad
sometimes about the constant work. When I travel a lot usually I'm just so
tired that I just want to go to my hotel room and sleep.
"After doing that for a couple of months you think, 'Why do I do this?
Where's the reward?' "
The 'Lizzie McGuire' star is keen to become a "serious actress" but is
frustrated that most directors can't see past her child star image.
She said: "They'll meet with me. They'll want to go somewhere and talk, ask
questions. Then they'll call and say, 'We really love her, she's great,
wow.' But they have no imagination.
"I know people look at me and think I'm just so mainstream, 'She's just a
blonde, young girl.' But I want to be really artistic."
The only exception is John Cusack who has cast Hilary as a pop star in his
new political satire 'War, Inc'.
The excited actress said: "She's a slutty, oversexed, b***h."
