The 'Spiderman' star had checked into Utah's Cirque Lodge Treatment Center last February for depression.
"Everybody in life goes through obstacles in different times of their life, and this year was my difficult time. It's part of life and it's just called growing up," People quoted Dunst, as saying.
She added: "What I have learned is if you make it out of this business and realize the whole bigger picture of it all, you are in a good spot. It's just seeing what is important and the bigger things in life."
And now, the star aspired to keep a balance between her private life and living in front of the cameras.
"It's not healthy to live that kind of life. I don't live in the spotlight and I don't live my life in front of the paparazzi. I live very comfortably and quietly as possible," she said.
