There are two schools of thought on stuttering and what will work for you depends on how you think about fluency. The first type is accepting that stuttering will happen and just relaxing and letting it happen without tension. If you observe and listen closely to people around you, others stutter and repeat all the time. It happens when we're nervous or uncomfortable, but it is not something we focus on when it doesn't happen to us all the time. The other type of therapy is where you learn specific strategies for speaking, breathing and speech rate to decrease the number of disfluent words. Sometimes, the best philosophy is to accept that stuttering is part of you and to stop fighting it so hard. A lot of stuttering is genetic and tends to run in families. You can message me if you have specific questions, but your best bet is to interview experienced therapists who know what they're doing. Most universities have experts in the field of stuttering, so you might want to start there. Good luck!
