lost one's mind
Became completely unhinged
To lose one's mind is to become insane or mentally unstable, or more commonly, to act in a way that suggests temporary irrationality: Have you lost your mind? You can't quit your job with no savings.
The phrase often expresses disbelief at someone's judgment rather than concern about actual mental illness.
It can also describe being overwhelmed by emotion: I lost my mind when I saw the bill.
