Washington: Demi Lovato has revealed that rehab has helped her understand who her real friends were.
The 20-year-old singer said that checking in to a treatment facility for the treatment of bulimia and self-harming in 2010 was a life-changing move for her, because these incidents made her realize who genuinely cares about her, Contactmusic reported, Contactmusic reported.
The `X Factor USA` judge told Company magazine that a couple of months before she went to rehab, she had a birthday party where there were around two hundred people and she considered all of them as her closest friends.
The` Give Your Heart a Break` star added that when she turned her phone on after being in rehab for three months, she expected a lot of text messages and phone calls but was surprised to see that there were only four texts.
She further revealed that this was a wake-up call for her.
The 20-year-old singer has cut most of her old friends out of her life and now she has only a small support group of reliable people.
Demi insisted that she doesn`t have loads of friends like she used to have before.
She added that now she has people who would accompany her to the hospital even if she breaks her leg in the middle of the night and would answer the phone at 4 am, if needed.
