So, first thing’s first… what are cognitive distortions? Cognitive distortions, a term first coined by David Burns in his 1981 book Feeling Good: The New Mood Therapy, are negative ways of thinking that are inaccurate, misinformed, and designed to increase negative feelings about ourselves, others, and the world around us. Basically, cognitive distortions are up to no good and can contribute greatly to the development of (and worsening of) eating disorders.
