Most emotional problems arise from faulty thinking, and the remedy is found in corrective actions. CBT is problem-focused, and it aims to help you get better in the long term, which is done by changing your unhealthy beliefs to their healthy counterparts. That is the reason why CBT is based on the understanding that by changing how we think about things (our cognitive processes), we can change the way we feel (our emotions), and the way we react (our behaviour).
It can help us learn how to overcome negative emotions and behaviours. The intent is to: help people clarify their emotions, behaviours and goals; identify the unhealthy beliefs that are at the heart of their emotional problems and sabotage their goals; Dispute them and replace them with their healthier version in order to get better through consistent and constructive action; finally, to generalise the change to other areas of life.
