Those who were hoping to catch one of Sinead O'Connor's upcoming performances were disappointed on Tuesday, as the singer has canceled the remainder of her U.S. tour.
As a note posted on her website explains, the "Nothing Compares 2 U" songstress hasn't been feeling well.
"With enormous regret I must announce that I have to cancel all touring for the year as [I] am very unwell from bipolar disorder," O'Connor reportedly wrote in a note on her website, which was then re-posted on a fansite. Her official website appeared to be suspended on Tuesday morning.
"As you all know I had a very serious breakdown between December and March and I had been advised not to go on tour," O'Connor reportedly continued. "But [I] didn't want to 'fail' or let anyone down as the tour was already booked to coincide with the album release. So very stupidly I ignored [my doctor's] advice to my great detriment, attempting to be stronger than I actually am."
O'Connor was set to play shows in Milwaukee, Chicago, Washington D.C., Philadelphia and New York in the coming weeks in support of her ninth studio album, "How About I Be Me (And You Be You)?" which was released in February.
"I apologize sincerely for any difficulties this may cause," O'Connor wrote, adding that she does hope to perform at a Curtis Mayfield tribute event in July.
The past few months have been a rough ride for O'Connor, who went through a whirlwind 16-day on-again, then off-again marriage last December, followed by a suicide attempt and requests for help via Twitter earlier this year.
