Robert Pattinson has opened up about relationships, fame and his severe anxiety in Australia's Sunday Style, The Huffington Post reported Monday.

Pattinson, the star of the Twilight series, spoke about his struggle with fame. The 27-year-old still has moments where he feels like a struggling actor who was just looking for a way to support himself in England.

"I just didn't expect any of this and I didn't ask for it," the actor said. "It was literally all luck. I just stumbled from job to job."

Pattinson also added that being a global superstar was not without its difficulties.  He worried about his mental state of being. He stressed it was difficult to remain sane.

"In the beginning I didn't even notice my life had changed so massively, because I was always working. I suppose eventually I got used to it," he said.

Pattinson said he was not used to the spectacle of the red carpet. He was still nervous at the appearances.

"I get a ton of anxiety, right up until the second I get out of the car to the event, when suddenly it completely dissipates. But up until that moment I'm a nut case," he said.

Pattinson also discussed matters of the heart. He said that he tried to be charitable with those who have hurt him.

"I don't ever feel the need to forgive or expect people to be. I judge people on their actions. I don't really care if it's wrong or right, I give them the benefit of the doubt. If they do something I can't be bothered to deal with, I just cut them out," Pattinson said.
