Sinead O'Connor says she is canceling "all touring" for the year due to her bipolar disorder, she reportedly announced on her website Monday (April 23).

The 45-year-old singer's website and Twitter acount are both no longer active, but a fan site has posted the statement that appeared on the site for a few minutes. After reportedly tweeting that there was "too much falseness" in showbiz and she wanted a "normal job," O'Connor wrote that she is "very unwell" and therefore canceling her 2012 tour.

"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," she reportedly wrote on her website Monday. "So very stupidly I ignored his advice to my great detriment, attempting to be stronger than I actually am. I apologise (sic) sincerely for any difficulties this may cause."

The post also said that O'Connor "hopes and plans" to appear at the Curtis Mayfield tribute in New York City's Lincoln Center on July 20.

The Irish singer split from therapist husband Barry Herridge in December after 16 days of marriage. O'Connor was set to tour this spring in support of her latest album -- "How About I Be Me (And You Be You)?" -- which was released in February, peaking at No. 115 on the Billboard 200 with 11,000 sold according to Nielsen SoundScan.
