Britney Spears told a judge on Wednesday that she wants to end the conservatorship that has governed her life for the last 13 years, calling it "abusive" and denouncing her father for exerting control over her life.

"I told the whole world I'm happy – it's a lie," she said. "I've been in denial... I am traumatised. I'm not happy. I can't sleep. I'm so angry it's insane."
