a vicious circle
a difficult situation that cannot be improved because one problem causes another problem that causes the first problem again I get depressed so I eat and then I gain weight which depresses me so I eat again - I'm caught in a vicious circle.
A series of events in which each problem creates another and worsens the original one. For example, The fatter I get, the unhappier I am, so I eat to cheer myself up, which makes me fatter yet-it's a vicious circle . This expression comes from the French cercle vicieux, which in philosophy means "a circular proof"-that is, the proof of one statement depends on a second statement, whose proof in turn depends on the first. One writer suggests that the English meaning of "vicious" helped the expression acquire its more pejorative present sense, used since 1839.
