Sinead O'Connor is leaving the stage and the spotlight to focus on her mental health, months after her struggles with bipolar disorder became public.
This week, the Irish singer has cancelled all her 2012 touring plans and shut down her website and Twitter account, the Seattle Post-Intelligencer reported.
"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," she explained to fans on her site before it was removed.
"Very stupidly I ignored his advice to my great detriment, attempting to be stronger than I actually am," she added.
Her decision to bow out of the music business followed her surprise cancellation of a performance in Munich Saturday.
"Any one have a job for a very clever woman with massive heart and courage, who adores people and has to escape music business as is very bad for her? Too much and too many long times away from home. All bad triggers for a woman with a mental illness. Can anyone come and take me home from Munich?" she tweeted at the time, the Irish Independent reported.
The 45-year-old — who rose to fame in the '90s with her hit "Nothing Compares 2 U" and to infamy when she tore up a picture of Pope John Paul II on "Saturday Night Live" — had just released a new record that was enjoying good reviews and sales.
"Smash" Goes Bollywood
O'Connor made headlines in December when she suddenly married, separated from and reunited with a drug counselor within a matter of weeks, The New York Times reported. They later separated again.
