The 25-year-old "Twilight" star says she has improved her bond with the media after learning to "give herself" to life, reported Marie Claire magazine.
"(I've) come out the other end not hardened, but strong. At one point, you just let go and give yourself to your life. I have finally managed that," she said.
The "Snow White and the Huntsman" actress also opened up about being "constantly anxious" when she was not in control.
"Between ages 15 and 20, it was really intense. I was constantly anxious. 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," she revealed.
