Demi Lovato is living proof that life gets better.
The "Really Don't Care" singer entered rehab in late 2010, and since then, she has been an advocate for people dealing with mental health issues. Lovato guest-edits and covers Seventeen's August 2014 issue, where she once again discusses her emotional journey and gives advice to those facing similar struggles.
"Since I went to treatment, there have been days when it's felt really easy, and I've felt great about where I am. But then I have moments when it's not. That's life," she says. "You can't just take your mind and your body into the shop and get it fixed. It doesn't come out repaired. It's not like a car. It takes time—pace yourself. Every day is a new opportunity to change your life and be who you want to be."
"I used to think that confidence came from what other people thought about me, and boys and everything else," the Camp Rock star tells the magazine. "But now I realize that confidence comes from what I feel about myself, and reassuring myself that I can do whatever I want and be whoever I want."
