"Unhinged"

"Unhinged" describes a person whose mental or emotional stability has become severely disturbed, often resulting in irrational or unpredictable behavior. It suggests they are no longer acting in a rational or controlled manner, possibly driven by intense anger, distress, or mental health issues. The term can also refer to a situation or object that appears to be dislodged or not functioning properly. In essence, calling someone "unhinged" implies they are exhibiting dangerous or erratic behavior that deviates markedly from normal or expected conduct.
