The 26-year-old singer was hospitalised after a suspected overdose and is currently receiving intensive treatment in a rehab facility, and her close friend and fellow musician Iggy has said that she's confident the star will be able to bounce back and use her experiences to help other people.
Iggy, 28, told People magazine: ''She needs her privacy, and it's this funny tightrope for her to walk because she is so vulnerable and honest, and she touches so many people with her honesty and her openness, so I don't know how she'll continue this. I know she'll find a way to share this story and turn it into something positive that other people can take from.''
Demi was previously an advocate for mental health after celebrating six years of sobriety earlier this year, but released new track 'Sober' in June in which she revealed she had relapsed.
Now the 'Sorry Not Sorry' hitmaker is back in rehab - after first completing a stint in 2010 - it has been claimed she doesn't want the journey to be easy, as she wants a program that will push her to the limits to make sure she changes her ways.
A source said: ''This is not her first rodeo. She doesn't want to feel like things are being handed to her. For Demi, this is a strength test.
''The rehab she is in is much more drill sergeant-esque. It's not nurturing. At places like Promises, you live on the beach and go horseback riding. That's not what Demi needs to put her in check.''
Recently, Demi was said to have jetted off to Chicago to meet with a therapist who specialises in addiction, which was set up for her through her current treatment centre.
It was claimed the star would be spending ''several months'' in rehab as part of an ''extensive'' program, but sources said she was already doing ''much better''.
They said: ''She will be in rehab for several months and is doing an extensive program to ensure she gets the help she needs.
''Demi is doing much better. She has become more open and is happy she is getting the help she needs, [as she now] grasps the severity of what happened and that she almost died.''
