I have gone. There are many ways to approach it. Desensitization (addressing fear), acceptance, changing your mindset in approaching conversation and situations (CBT), addressing how your body reacts to situations (fight/flight/freeze) via somatic work. And on top of all that, working on past trauma. I firmly believe stuttering has the ability to cause CPTSD. IMO it is essential to address these things and then if you do decide to work in your speech, it makes therapy more effective
