The Sinèad O’Connor concert scheduled for May 23 at the House of Blues in Boston has been canceled along with all of the dates of her upcoming tour in support of the new record “How About I Be Me (And You Be You).”

Here’s what was posted on O’Connor’s Facebook page earlier today:

“With enormous regret I must announce that I have to cancel all touring for the year as am very unwell due to bipolar 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.”
