Miley vs. Sinead and more of the biggest celeb feuds

"You've said on Matt Lauer's show (where you again refer to me as 'crazy') that you don't understand why I have been upset with you," she said. "Until you exposed me (And Amanda Bynes) to abuse on the grounds of my having sought help (extremely coherently) to save my life, when experiencing suicidal compulsion as a side effect of a medication called Tegretol, I had no problem with you whatsoever. I would very much like you please to apologise to myself and Amanda Bynes for having perpetuated abuse of both of us on the grounds that Amanda has had 'mental health issues' and that I experienced suicidal compulsion and was open about seeking help in order to save my life.

"Please do the right thing. You will actually save lives by doing so," O'Connor continued. "There are people who will NOT die tonight, if you are brave enough to state that there is nothing whatsoever wrong with any person seeking publicly or privately, help, in order to stay alive. And that there are no circumstances under which it is acceptable for anyone to use mental illness as a stick with which to beat people."
