Billie Eilish has spoken about her struggles with mental health, revealing that she suffered from depression and body dysmorphia.

The 17-year-old singer-songwriter said life became difficult for her aged 12 when she joined a competitive dance company.

She told Rolling Stone magazine: "That was probably when I was the most insecure. I wasn't as confident. I couldn’t speak and just be normal. When I think about it or see pictures of me then, I was so not OK with who I was."

"At dance, you wear really tiny clothes," she continued. "And I've never felt comfortable in really tiny clothes.

"I was always worried about my appearance. That was the peak of my body dysmorphia. I couldn't look in the mirror at all."

The Bad Guy hitmaker said she had to quit dance after rupturing the growth plate in her hip, which was "when the depression started".

"It sent me down a hole. I went through a whole self-harming phase - we don't have to go into it. But the gist of it was, I felt like I deserved to be in pain," she said.

Eilish added: "When anyone else thinks about Billie Eilish at 14, they think of all the good things that happened.

"But all I can think of is how miserable I was. How completely distraught and confused.

"13 to 16 was pretty rough."

The music sensation said that 17 has been the best year of her life.

"I haven't been depressed in a minute, which is great," she said. "17 has probably been the best year of my life. I’ve liked 17."
