The 21-year-old singer admits that sometimes being in the spotlight can have it's downside, but explains that being able to inspire and help so many people makes it worth it, reported E! Online.
"Yeah it's been difficult," Lovato says of walking the fine line between wanting privacy but also wanting to be there for her fans.
"I'm not the type of person that loves the fame aspect of it. I would rather sacrifice my privacy to help people, not just with my music. Strictly from this point of view, from an inspirational point of view of sharing my story. I know that I have a purpose in the world," she added.
"I'm thrilled to have the opportunity to share this book. It is my hope that these affirmations will help readers to remain strong and hopeful, even when that seems impossible," she said.
