The clip led to fans rushing to the motel, in Hackensack, New Jersey, offering to help, and to her musical contemporary Annie Lennox asking where O’Connor’s friends and family were.

DailyMail.com can reveal that O’Connor is now in a hospital in New Jersey, a fact which will offer further reassurance to fans after a friend used the singer’s Facebook page to say she was ‘surrounded by love and receiving the best of care’.
The singer’s troubles have been fueled by a messy and bitter legal dispute in Ireland with her manager, a former lover who she is now involved in litigation with.
O’Connor had spent time in a suburb of Chicago last year being cared for by friends, and has also spent time seeking help for her mental health issues at a facility in California.
Mental health advocates have said they hope that the video has a positive impact on others with mental health problems.
As the clip went viral fans rushed to the motel on Tuesday, where O’Connor had left her car, but she had already gone. Local police said they had checked on her welfare.
And later on Tuesday, a post on her Facebook page said: ‘Hi everybody, I am posting at Sinead’s request, to let everyone who loves her know she is safe, and she is not suicidal.
‘She is surrounded by love and receiving the best of care. She asked for this to be posted knowing you are concerned for her. I won’t respond to any questions, so please understand. I hope this comforts those of you were concerned.’
The action is being taken in Ireland by Fachtna O’Ceallaigh, 70, who met O’Connor in the Eighties when she was 17 and steered her to stardom in a partnership that lasted until 2012.
He claims O’Connor terminated their business relationship without warning and defamed him in a letter published on her website and a fan’s website. He is seeking damages of around ¤500,000 (£452,000).
O’Connor denies the claims but, according to her lawyer, who appeared at a pre-trial hearing at Dublin High Court ten days ago, ill health has delayed her ability to defend herself.
Speaking about their romantic relationship in previous interviews, she described them both as ‘driven people’: ‘You can see that from what we achieved together,’ she said.
In the past, O’Ceallaigh, who also managed U2 and Bob Geldof’s Boomtown Rats, has always been sympathetic to his muse.
‘The same thing that makes her great, that generates joy and fulfilment in her work, has also caused great pain and difficulty for her,’ he said.
‘It is incredibly painful to see her living her life the way she lives it sometimes.’
But the pair’s business split — which came, according to sources, via a ‘very colorful email from Sinead’ while on tour in Germany trying to reboot her career – changed things.
Since then O’Connor has largely stayed away from Ireland, where her four children – Jake, 29, Roison, 21, Sahne, 13, and Yeshua, 10, live.
He lives there with his wife Charlotte and their children.
O’Connor and Walker performed together in Chicago in January 2016 in a tribute to the death of David Bowie. It is the last known time O’Connor sang on stage.
Last May, in an echo of her current predicament, O’Connor sparked concerns for her welfare when she went for a bike ride from the Walkers’ home, and did not return, prompting a major police search.
