Demi Lovato didn't care about the results of cutting herself when she was a self-harmer.

'The X Factor' USA judge admitted that she needed to do "something physical" in order to cope with her negative feelings.

She said: "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."

The 19-year-old star told American Self magazine's August issue. "I cut myself to take my mind off that. I just didn't care what happened. I had no fear."

The former Disney actress has been making positive strides on a daily basis.

She continued: "I make time for myself and meditate. I've spent the past two years getting over an eating disorder and issues like self-harming and bipolar disorder. I have to work on this stuff every day. I'm reminded of that whenever I eat or feel down."

The singer has also made another habit change recently that she believes is part of her new, healthier lifestyle.

She confessed: "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."
