The actress spoke to Marie Claire in the August 2015 issue where she opened up on how stressful it was to be a public figure in her early 20's. Even though she survived those years, it's was something that Stewart had to stay tough through.

"I lit my universe on fire and I watched it burn. Speaking very candidly, it was a really traumatic period in my early 20s that kick-started something in me that was a bit more...feral," the star said via E! News. "The public kind of burned me at the stake. But that's okay, I can take it. I'm not dead."

Was Kristen Stewart Planning On Living With Rumored Girlfriend Alicia Cargile?

Stewart became a massive hit in the entertainment industry when she landed the role of Bella Swan in the Twilight movies where she dated her on-screen lover Robert Pattinson. The actress pointed out how some of these years gave her anxiety.

"Between ages 15 and 20, it was really intense. I was constantly anxious," she said. "I was kind of a control freak. If I didn't know how something was going to turn out, I would make myself ill, or just be locked up or inhibited in a way that was really debilitating."

Stewart said that she was able to push through this by letting it go.

"I have finally managed that and I get so much more out of life," she said. "I've lived hard for such a young person, and I've done that to myself- but I've come out the other end not hardened but strong."
