London - Sinead O'Connor cancelled her tour because her management worked her too hard.
The Nothing Compares 2 U singer - who has openly discussed her battle with mental health in recent months - slammed the "inhumane" pressure she was under, and claims she was blamed for her illness.
She wrote in a letter on her website: "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.
'Lost her voice'
"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."
Sinead also claimed she lost her voice because her management failed to supply her with the correct on-stage equipment, and then blamed her when she fell ill.
She explained: "An example of the type of punishing schedule I referred to is the following after three shows in Los Angeles I had lost my voice.
"This was because my proper equipment was not ordered. I had only two monitors on the floor. And could not hear myself singing above the big loud band. There were no side fills.
"I managed to bluff my way through the three shows and still get good reviews, by some miracle.
"When I complained that I needed the right equipment in order to do my job, certain employees around me insisted that it was my responsibility that I had lost my voice because I was not looking after myself. This was absolutely not the case.
"I have never in 30 years of being a singer lost my voice. I lost my voice because I had had to shout above the band because of not having the right equipment."
