Cognitive Behavioral Therapy -- aka Cake or Death

Cognitive-Behavioral Therapy (CBT) is a... treatment that focuses on patterns of thinking that are maladaptive and the beliefs that underlie such thinking... In CBT, the individual is encouraged to view such beliefs as hypotheses rather than facts and to test out such beliefs by running experiments. Furthermore, those in distress are encouraged to monitor and log thoughts that pop into their minds (called "automatic thoughts") in order to enable them to determine what patterns of biases in thinking may exist and to develop more adaptive alternatives to their thoughts. -- NAMI.org
