Cognitive Behavior Therapy (CBT) is a psychotherapy approach emphasizing the intricate interplay between thoughts, emotions, and behaviors. The theory posits that our cognitive interpretations of situations influence our emotional states, which in turn dictate our actions. A singular event can be perceived in multiple ways, and depending on that perception, it can elicit a range of emotional and behavioral responses.

This interconnectedness forms the foundation of CBT. For instance, facing a challenge, a thought like "I'll surely fail" can lead to feelings of anxiety, culminating in avoidance. Conversely, thinking "I'll do my best" might foster optimism, prompting constructive action. CBT equips individuals to discern these links, enabling them to consciously reshape their thoughts, and consequently, their emotions and behaviors for improved mental well-being.
