Pop singer Britney Spears urged a US judge Wednesday to end a controversial guardianship that has given her father control over her affairs since 2008. "I just want my life back. It's been 13 years and it's enough," she told a court hearing in Los Angeles during an emotional 20-minute address via videolink. "I truly believe this conservatorship is abusive," said Spears, who asserted that the legal arrangement had left her "traumatized" and "depressed." pdh/ec
