On reading about Cognitive-Behavioural Therapy (CBT) I encounter
But, if you feel sad after a friend cancels your lunch plans and you begin to think there’s obviously something seriously wrong with you and no one likes you, this is problematic because this thought is extreme and not based on reality.
This makes sense because concluding that none likes you from canceling lunch is overestimation.
But my question is different: how or why are we generating these unrealistic thoughts in the first place? Especially given that after some challenging these thoughts, we can correct them ourselves. So if we can correct them ourselves after challenging them, why do we generate these unrealistic thoughts in the first place, and not the correct ones?
