Sinead O'Connor took a career break because of "disgusting" people in the music industry.
The 'Nothing Compares 2 U' singer received rave reviews for her 2012 album, 'How About I Be Me (And You Be You)' but early on in her tour, Sinead was diagnosed with bipolar disorder.
Now the 47-year-old musician has spoken out against her diagnosis and questions the motives of the people who were meant to be looking after her.
Talking to The Sun newspaper, she explained: "I had to leave the tour for genuine reasons of being unwell as a result of medication I was put on for a condition we're not sure I ever had. I had a reaction to the medication.
"With people in the business everything became so horrible. I've never seen anything f***ing like it in my life. Disgusting really. The worst of the worst."
Sinead - who is now preparing to release her new album, 'I'm Not Bossy, I'm The Boss' - admitted falling "madly in love" with music again had saved her.
She said: "It was the kind of stuff that made you want to jump of a roof. I thought if I didn't fall madly in love with music again I'd be in trouble, so that's what I did."
The shaven-haired songstress revealed the inspiration behind her tenth studio album came from the 'Ban Bossy Campaign', which is backed by the likes of Beyonce and the US Girl Scouts.
Sinead shared: "In the music business, artists are treated as if we are working for the people who are in fact working for us."
