I don't much like trendy buzz words and clichés, but gaslighting is a useful concept, from the old movie Gaslight with Charles Boyer and Ingrid Bergman.

I particularly don't like words and phrases newly created when there is already a perfectly good one, but I don't know of any word that can be substituted for gaslighting. If you can, please let me know.

gaslight

verb (gaslights, gaslighting, gaslighted)

[with object] manipulate (someone) by psychological means into questioning their own sanity: in the first episode, Karen Valentine is being gaslighted by her husband.[from the storyline of the movie Gaslight (1944), in which a man psychologically manipulates his wife into believing that she is going insane.]
