You’re kind of living in this alternate reality,” Contactmusic quoted the singer as telling Oprah Winfrey on her chat show. “I started getting really paranoid. So I went one day into this church and I thought that the FBI and the SWAT teams were outside the church ... so I had a conversation with God ... and I said, ‘Alright, if I go out there and the FBI and the SWAT team’s not out there, then it’s the drugs and I’m stopping.’” she said. “I went outside of the church ... and there was no SWAT team, there was no FBI, just me and God. And I kept my promise. That day. That was it,” she added.
