I’m in grad school for speech therapy right now. What we know about stuttering- it is genetic and there is a neurophysiological component to it. It’s not caused by environmental trauma but stress can make it worse on a given day, but it’s not the cause. It’s a timing cue pattern in the basal ganglia. There was a horrific study that was done in the 1939 called [the Monster Study](https://en.m.wikipedia.org/wiki/Monster_Study) where they separated orphans into two groups, one that would receive positive feedback, and one that would receive negative, where they would get belittled for speech imperfections for six months. It was a terrible study and the biggest effect it had on the children was psychological trauma. Psychological trauma can change speech patterns within typical limits but it didn’t cause stuttering. I would recommend finding a local support group for people who stutter. It amazes me how long many adults go before they have the chance to meet someone else who stutters. You could also see a speech therapist *who specializes in fluency/stuttering disorders* (not all SLPs have extensive training in this area) and they can help you with techniques to gain control of the stutter in certain situations. Your stutter won’t fully go away, but therapists can help you with the management of it to lessen the severity. Secondary behaviors (e.g. blinking eyes, grimacing, stomping foot, etc) are treatable though. A good therapist will also have a component on Acceptance and Commitment Therapy, which can help reduce anxiety around the stutter, which can help reduce the severity of it. PM me if you’d like some more resources.
