Equivalents in other languages

Origin: Rooted in an old idea, older than English itself, that overwhelming emotion could push the mind or soul briefly outside the body — "beside" here carries its older sense of "outside," so being "beside oneself" meant no longer occupying your normal, settled state of mind. The image may ultimately trace to Greek parankia, madness, built from para (beside) and nous (mind), the same root that gives English "paranoia." William Caxton's 1490 English translation of Virgil's Aeneid already has "mad and beside herself," and the King James Bible carries the phrase forward in Acts 26:24, describing Paul's accusers as certain he had lost his mind.
