Demi Lovato has relapsed into self-harming and throwing up
The `Skyscraper` singer - who was admitted to a treatment facility for three months in November 2010 to receive help for an eating disorder and self-harming - admitted she can never fully recover from her issues but is doing everything she can to keep them under control.
Speaking in her new `Stay Strong` documentary on MTV, she said: "I cannot tell you that I have not thrown up since treatment. I cannot tell you that I have not cut myself since treatment. I`m not perfect.
"An addiction is an obsession, something that takes over your mind and your every thought. You think that you can`t live without it. For me, it was not eating and purging and self-harming.
Demi - who was also diagnosed with bipolar disorder while in treatment - added that her troubles stemmed from insecurity and feeling she was "living a lie".
She added: "[I was] looking in the mirror and never feeling good enough. I felt like I was living a lie...I was dealing with all this pain, emotionally. And I felt guilt and shame. I decided to take it out on myself. I harmed myself."
Although Demi shot to fame on Disney show `Sonny with a Chance`, she has no immediate plans to return to TV and will instead focus on her music and her fans, who she dubbed the Lovatics.
She said: "If you took away music, I wouldn`t have a reason to live.
Every time someone asks me for a picture or an autograph, even if I`m having a bad day and I`m in a bad mood, I remember, `You`re nothing without this person`. They make it special."
