Pathological is a memoir that tells the story of the factors that led to, and then consequences and aftermath of, the six misdiagnoses Sarah Fay received over a twenty-five year period (anorexia, major depression disorder, anxiety disorder, attention deficit hyperactivity disorder, obsessive-compulsive disorder, and bipolar disorder). The standard method used to diagnose these disorders is massively flawed, and Sarah launches a deep investigation to expose the truth.
