Singer Miley Cyrus has said she suffered from depression and once she had to be physically saved by her father Billy Ray, who burst through a locked door to rescue her.

`I went through a time where I was really depressed, like, I locked myself in my room and my dad had to break my door down," mirror.co.uk quoted Cyrus as saying.

The 21-year-old singer said the illness was triggered by the insecurity she felt when she was suffering from acne.

`It was a lot to do with...I had really bad skin and I felt really bullied because of that. But I never was depressed because of the way someone else made me feel. I just was depressed," added Cyrus.
