US pop star Britney Spears has launched a blistering attack on the "abusive" conservatorship that has controlled her life for 13 years.
She said she was traumatised and cried every day, telling a judge in Los Angeles: "I just want my life back".
Spears, 39, also said she had been denied the right to have more children and was put on the psychiatric drug lithium against her wishes.
Her father was granted control over her affairs by court order in 2008.
The order was granted after the star was put in hospital amid concerns over her mental health, and it has been extended for more than a decade since.
The special hearing on Wednesday was the first time Spears has spoken in open court about her case. Los Angeles Superior Court Judge Brenda Penny thanked Spears for her "courageous" words during the proceedings.
It followed much speculation about the pop star's situation, with fans eagerly combing her social media output for clues. A fan-led movement, known as #FreeBritney, has campaigned for her legal freedom for years.
But a long legal process is likely before any decision is made on ending the conservatorship, the Associated Press reports.
Spears delivered an impassioned address which lasted for more than 20 minutes. After launching into her speech, she was asked by the judge to slow down and later said she wished she could stay on the phone "forever" to avoid returning to her life where she was surrounded by people who said no to her.
Spears told the court she wanted the conservatorship to end and described the arrangement as "embarrassing and humiliating".
What is a conservatorship?
A conservatorship is granted by a court for individuals who are unable to make their own decisions, such as those with dementia or other mental illnesses.
Spears' conservatorship is split into two parts - one is for her estate and financial affairs, the other is for her as a person.
Under the agreement, the pop star has not controlled her finances since 2008. That is around the time she began to behave erratically amid her divorce from Kevin Federline and a custody battle over their children.
The star made headlines in a series of public incidents, including shaving her head, and she was twice admitted to hospital.
