When she's on stage, Norway's Eurovision entry, Agnete, is confident and assured.

Offstage, the 21-year-old singer struggles daily with depression. She's now cancelled all interviews in the run-up to the contest.

"We made room for her to focus," says Stig Karlsen, the head of Norway's Eurovision delegation.

"She's a strong, intelligent girl who's taking control of her own situation."

"She's been open about her bipolarity and health issues because it's not that common to talk about it."

"I think she's an inspiration," Karlsen adds.

"In Norway, she's very successful and she's a role model for dealing with her challenges."

Agnete's performing her single Icebreaker in Thursday's second semi-final in the Swedish capital Stockholm.

At the Eurovision Song Contest, meeting fans, endless press interviews and mini appearances around Stockholm are all part of the build-up.

But Agnete says she hopes people can understand that the thing she loves most - the singing - is the only thing she can focus on for the time being.

With an audience of 200 million, you might think performing would be the trigger for anxiety and nerves. Not so.

"The stage is her comfort zone," says Karlsen.

"If she's in a space where she can be creative and perform and sing - that's the best place for her to be."

In the past, Agnete's described the "hell" of her mental health. She told the website VG: "I can't always control my thoughts as much as I'd like to."

Appearing at Eurovision is something Agnete has always dreamt about, according to Stig Karlsen.

"She tells me every day that she's going to win the contest."
