Sinead O'Connor cancels tour on doctor's orders

The balance of Sinead O'Connor's 2012 tour has been cancelled, including shows in Chicago, New York, Boston, Montreal and Toronto, due to the singer's bi-polar disorder.

O'Connor released a statement addressing the situation:

With enormous regret I must announce that I have to cancel all touring for the year as am very unwell due to bi polar disorder. As you all know I had a very serious breakdown between December and March and I had been advised by my doctor not to go on tour but didn’t want to ‘fail’ or let anyone down as the tour was already booked to coincide with album release. So very stupidly I ignored his advice to my great detriment, attempting to be stronger than I actually am. I apologise sincerely for any difficulties this may cause.

While touring will be cancelled I do hope and plan to appear at the Curtis Mayfield tribute in The Lincoln Centre in July. — Sinéad
