Sinead O'Connor said in an online video she is living in a motel and is suicidal.
The 50-year-old Irish singer says in the video posted Thursday that she was staying alive for the sake of others and if it were up to her, she'd "be gone."
O'Connor said she was living in a motel "in the arse end of New Jersey" and later posted the address of a Travelodge in South Hackensack.
South Hackensack Police Capt. Robert Kaiser says officers conducted a welfare check, but O'Connor wasn't in her room at the time. He says she is no longer staying there and police don't know where she is currently living.
A follow-up Facebook post said to be made on O'Connor's behalf late Monday said the singer was OK.
In the video, the troubled singer said as she wept, "I'm all by myself. And there’s absolutely nobody in my life except my doctor, my psychiatrist, the sweetest man on earth, who says I’m his hero, and that’s about the only thing keeping me alive at the moment … and that’s kind of pathetic."
