rumination may involve repeated thinking that “I am worthless, I am a failure,” supplemented by recall of experiences, such as a poor evaluation of a piece of work you delivered.

Sticky mind-wandering can take the form of recurrent worries, for example, about not being good enough, about their children, their future, and so on.
