While filming “Carrie” in 2013, the now-18-year-old star admits that she let negative comments on social media affect her confidence. “I felt fat; I felt not pretty,” she tells Marie Claire in it’s February issue. “I felt like I didn’t really know who I was. I was so confused; I was scared. I had bad acne. I felt incredibly insecure.”

While the “Fifth Wave” star had a tough time in her mid-teens, she’s definitely come into her own. “I’m so free now. I don’t know what happened, but when I turned 17, this huge weight was lifted off my shoulders,” she says. “I’m so open; I have a good time; I don’t worry about what people say about me. I know who I am, who I want to be, what I want to portray myself as, what I want people to think of me.”

Not only did Chloe have to navigate the pitfalls of fame, but she also was dealing with major changes at home.

When her parents got divorced, Moretz says “it made me harder on myself. [It] was as heavy as you can get to dismantle a family, for sure. He just left, so it’s like you have to fend for yourself.”

“When you’re betrayed by someone that is a bloodline, you start to beware trusting people and to protect yourself at all costs,” she adds. “For a long time, I did that too much. I wasn’t letting people in.”

Another aspect of her life that she’s not quite ready explore is her dating life. “I don’t want to date older people, because I’m 18 and older people are more serious. Then I kind of realized, ‘I’ll go on dates. Why not?’ And that’s kind of how I am right now,” she declares. “I’m not looking for a while. At least until I’m, like, 23.”
