The `Harry Potter` actress - who shot to fame at the age of 11 when she first appeared in the wizard franchise - admitted while she has been through a lot in her life, she often still feels "incredibly young and very naïve".
She said: "I`m this very weird mix. In some senses, I feel as if I`m 100 years old. In others, I still feel incredibly young, very naïve and as if I haven`t seen much of the world at all. I`ve been incredibly protected, but in other ways I`ve had to be in situations that nobody my age would.
"Sometimes I think I`m the worst person in the world to be in the situation I`m in. I`m shy, I`m sensitive and I`m self-critical. It`s a terrible combination."
The 21-year-old beauty also thinks her notoriety "intimidates" members of the opposite sex, because she is never pursued by men.
Emma added to Style magazine: "I say to my friends, `Why hasn`t X called me? Why doesn`t anyone ever pursue me?` They`re like, `Probably because they`re intimidated`.
"It must be the fame wall. It must be the circus that goes around me. Me, as a person, I find it hard to believe I would be intimidating."
