Demi Lovato had suicidal thoughts when she was just seven.

The 25-year-old singer/songwriter has battled various mental health issues during her life - including bipolar disorder, schizophrenia, depression, and anxiety - during her life, and has admitted she first felt suicidal during her youth.

In an interview with Dr. Phil, Demi explained: ''The very first time I was suicidal was when I was seven. I had this fascination with death.

''I have experienced things that I have not talked about, and I don't know if I ever will talk about. But at seven, I knew that if I were to take my own life, that the pain would end.''

Demi revealed that her suicidal thoughts were triggered by bullying.

And since then, she has experienced similarly dark thoughts as a result of emotional turmoil and trauma.

The 'Sorry Not Sorry' hitmaker said: ''It came back several times - when I was struggling with depression, my bipolar disorder. And there was a while there when my mom was afraid to wake me up in the mornings because she didn't know if she opened the door if I would be alive or not. Because every time I cut, it got deeper and deeper.''

The brunette beauty recently celebrated six years of sobriety, but she's admitted that her eating disorder has proven harder to battle than her drink and drugs issues.

She said: ''I think the everlasting addiction in my life has been food. My eating disorder started when I was very young. That's something that I deal with on a daily basis. It's kind of the last thing to go.

''I feel like I've conquered my addiction and alcoholism, where I don't even think about it anymore. But my struggles with my food issues are something that I still deal with. But I'm growing, and I'm in a really good place today.''
