As the "Twilight" publicity machine ramps up again in advance of the June release of [movie id="420622"]"Eclipse,"[/movie] Kristen Stewart has spoken out again about the difficulty of being in the spotlight, from dealing with paparazzi to contending with overzealous fans to bristling against a public perception that she takes her good fortune for granted.

"I hate it when they say I don't give a sh--, because nobody cares more than I do," she says in the new issue of Elle magazine. "I'm telling you, I don't know anybody who does this that gives a sh-- more than I do."

But one thing Stewart doesn't care for are those hectic red carpet premieres -- all those screaming photogs, clamoring journalists and forced interactions -- that have become the norm for every film she makes. It's enough to leave her on the verge of tears, she admits.

"People say that I'm miserable all the time. It's not that I'm miserable, it's just that somebody's yelling at me," she said of walking a carpet. "I literally, sometimes, have to keep myself from crying. ... It's a physical reaction to the energy that's thrown at you."

And she doesn't just encounter that negative energy at frenzied premieres. The spotlight is on her wherever she goes. "It's insane!" she said. "Once somebody finds out, you have to get the hell out of wherever you are. People freak out. And the photographers, they're vicious. They're mean. They're like thugs. I don't event want to drive around by myself anymore. It's f---ing dangerous.

"Somebody knocked on my hotel room door and asked for a light, then said that they were a big fan," she recalled. "I was like, 'Do you really need me to light your cigarette? How do you know what room I'm in?' I can't be by myself, and I like being by myself."

Though she is thrust into the public eye, with people snapping photos and trying to learn every detail of her life, Stewart draws the line when it comes to talking about co-stars Robert Pattinson and Taylor Lautner. "I would never cheapen my relationships by talking about them," she said. "People say, 'Just say who you're dating. Then people will stop being so ravenous about it.' It's like, No they won't! They'll ask for specifics."
