What does it mean do go through a complete CBT? without using meds?

is a psychotherapy based on modifying cognitions, assumptions, beliefs and behaviors, with the aim of influencing disturbed emotions. The general approach developed out of behavior modification, Cognitive Therapy and Rational Emotive Behavior Therapy, and has become widely used to treat various kinds of neurosis and psychopathology, including mood disorders and anxiety disorders.

CBT is commonly based on the idea that how we think (cognition), how we feel (emotion and affect), and how we act (behavior) all interact and go together. Specifically, that our thoughts influence our feelings and behavior, our feelings influence our behavior and thoughts and our behavior influence our emotions and thoughts. These modalities are therefore interrelated, and change in one modality will in all probability influence at least one of the others.[
