Demi Lovato Says Says She's 'Not Fixed...But Learning': See More Successfully Rehabbed Stars (PHOTOS)
The magazine touches on reports that Demi was using cocaine, but she was reluctant to go into detail.
"It's something I don't really want to talk about," she says. "What I can say is that I was depressed. I would come off stage in front of 18,000 people and suddenly be alone in a hotel room. I'd come crashing down and would try to find a way to recreate that feeling, to stay 'up'."
Now she realizes she could have continued down the wrong path at the cost of her life.
"Being a celebrity can be dangerous," she adds. "Nobody says 'no'. That's why so many end up overdosing and dying. It could definitely have happened to me."
Now, she's on the road to recovery, but it's one she knows is an uphill hike.
"I'm not saying I'm perfect, or fixed, but I am learning to love and accept myself. My outlook is more positive and I am happy," she says.
Demi certainly isn't alone in her struggles. Many of Hollywood's finest have battled addiction -- and if these stars in our Successfully Rehabbed gallery are any indication, it's totally possible to hit rock bottom only to soar back up to the top!
