The Nothing Compares 2 U singer, who has a history of mental health problems, went online to ask followers to put her in touch with psychiatrists in Dublin who could help.

She admitted that the controversy over her romance with fourth husband Barry Herridge had sent her into a meltdown.

The pair separated just 16 days after they married, but they have reunited since.

She tweeted that she needed “urgent” psychiatric help, but didn’t want to check herself into a mental health facility.

She said: “i realise i will be in trouble 4 doing this but.. ireland is a VERY hard place to find help in. So having tried other ways 1st im asking

“does any1 know a psychiatrist in dublin or wicklow who could urgently see me today please? im really un-well… and in danger.

“the sindo article about them trying to lose barry his job and every1 being shit to him 4 marrying me has spun me off and im ill

“and i desperately need to get back on meds today. am in serious danger. please e mail me if u know or are

“a psychiatrist who can help me today… dont tweet i b away from computer i broke ankle have to go casualty.

She then tweeted:  “me dont wanna leave me kids. or fuck up me work. im sorry worrying any1.. is just am sick and ireland shit for finding help cant think of any other way.”

This isn’t the first time O’Connor has shocked her Twitter followers – she has previously advertised on the site for sex before meeting Herridge and marrying him in Las Vegas.
