Since Demi Lovato checked herself into a treatment facility in late 2010, the "Skyscraper" singer has been fairly forthcoming about her struggles with bulimia and self-harm. But in the August issue of Self magazine, Lovato reveals it was her anxiety that led her to cut herself: "There were times I felt so anxious, almost like I was crawling out of my skin, that if I didn't do something physical to match the way I felt inside, I would explode. I cut myself to take my mind off that. I just didn't care what happened. I had no fear."

After leaving treatment in early 2011, Lovato released her latest album, Unbroken, and hit the road this summer for a North American tour. She also joined The X Factor as a judge alongside Britney Spears. But despite how hectic it might get, Demi isn't letting her busy new schedule stress her out. The singer's finding new ways to relax: "I make time for myself and meditate. And I haven't used my cell in three months! Subconsciously, it was a crutch. When a room gets quiet, what do you do? Grab your phone! Now I can sit and have conversations with people." No Instagram for 90 days? You're a bigger woman than us, Demi.
