Sinead O’Connor blames bad management for the cancellation of her 2012 tour in an open letter on her website, where she tries to shed more light on what happened.

“My widely documented and extreme illness of the last nine months, which involved a suicide attempt on January 10, 2012 was not taken into consideration at any stage during recent scheduling of my promo tours or concert tours concerning my most recent album,” she writes. “Schedules were set without having been run by me, while I was in the midst of a very serious breakdown. I was treated as if it was my own fault I wasn’t managing and I was responsible for it.”

“Expectations of me were unreasonable in my opinion and even at times inhumane. And everyone (apart from my band) working for me remained very far from presenting themselves as any kind of support either on the road or off,” she adds.

The singer also addresses her issues receiving a visa to work in America, problems with her medication, and how her manager broke an agreement in her contract that keeps her from being on the road for more than 10 days at a time.
