Most people tend to react similarly to depression. When they feel down, they lose interest in doing things and enjoying them. The tendency is so prevalent that lack of interest—in people, outings, and even food—is recognized as one of the five clinical signs of depression. “When people are feeling depressed, they end up withdrawing, becoming more internal, becoming more lethargic,” said Kelly Klump, who teaches psychology at Michigan State University.
But there also exists a subset of people who tend to exhibit a different reaction. For these people, depression breeds high levels of impulsivity. They do things they wouldn’t otherwise do.
Like opening a pint of ice cream, and polishing it off.
