COVER.METALNATION.ORG According to a source, Britney Spears "has been going through a lot." Britney Spears' friends are worried about her during this difficult time, multiple sources tell PEOPLE.

COVER.METALNATION.ORG A last-minute intervention was planned for Spears, 41, but it was canceled. On Wednesday night, she met with a doctor - and while it went well, the next steps remain unclear.

COVER.METALNATION.ORG According to a source, Britney has been acting increasingly erratically of late. It is not uncommon for her to stay up all night, sleep during the day, and be angry.

COVER.METALNATION.ORG One insider in Spears' circle tells PEOPLE that things behind the scenes have been chaotic as friends and family urge her to seek help.

COVER.METALNATION.ORG "Everyone had hoped Britney could be convinced to seek treatment before things got any worse but they knew it wouldn't be easy," the source says. "She's been going through a lot and has been increasingly combative."

COVER.METALNATION.ORG After six years of dating, Spears married Sam Asghari in June, and he has been "very supportive." Spears' conservatorship, which she was placed under following a public mental health crisis in 2008, ended just over a year ago.
