Evidence-based CBT is the world's most well-researched method of psychotherapeutic treatment. Extensive studies have shown it can do more than merely suppress symptoms, but also resolve them.
How does it work? Basically, our thoughts lead to emotions, and our emotions lead to behaviors. To break this cycle, there are opportunities at each juncture, but when possible we modify the thinking so as to change the emotion and behavior. Please see here for more information on how CBT works, including an example of someone with social anxiety and irritable bowel syndrome (IBS).
