Dunst -- a former child actress who has starred in the films "Interview with the Vampire," "Wag the Dog," "Eternal Sunshine of the Spotless Mind," "Marie Antoinette" and the "Spider-Man" trilogy -- reportedly underwent treatment at Utah's Cirque Lodge Treatment Center in February.
"I think that everybody in life probably goes through obstacles at different times in life. I wouldn't really call them obstacles, I think that's just called growing up, and I think it's hard to be in the industry at such a young age," Dunst, 26, told reporters in New York this week, while promoting her new film "How to Lose Friends and Alienate People."
"Actors are a pretty funny group of people and if you can make it out and realize the whole bigger picture of it all, I think that you are in a good spot," she said.
Asked what it is like to live in the spotlight, Dunst said: "I don't. I live very comfortably. I'm very grounded with my friends and my family and the people who work around me, so to me, it's just about not having people around you who want to use you for the wrong (reasons.)"
