HACKENSACK -- Irish singer-songwriter Sinead O' Connor posted a troubling video to her Facebook page Thursday, detailing her recent struggles with mental illness from a motel in what she describes as "the arse end of New Jersey."
PageSix.com reports O'Connor is staying at a Travelodge motel in Hackensack, while undergoing psychiatric treatment for "three mental illnesses."
Through tears the 50-year-old singer best known for her 1990 hit "Nothing Compares 2 U" laments the fact that she is alone and has been abandoned by her family.
"I'm really sad, I shouldn't be here and I know I'm just one of millions ... that should be our f***ing catchphrase -- why are we alone?"
O'Connor, who has said she suffers from bipolar disorder and has reportedly threatened suicide before, also discusses the separation from her youngest two children Shane and Yeshua (born in 2004 and 2006).
She speaks of arguments with unidentified men "who've got my kids, you know, and I can't get anywhere near, and they're not even fighting for the kids' sake."
Earlier in the 12-minute video, O'Connor says that due to her mental illness, no one validates her feelings and treats her unfairly.
"I want everyone to know what it's like, that's why I'm making this video," she says.
