I had seen multiple therapists (psychologist, speech therapist,...,) all try to linked that to my childhood and my parents divorce. I think it was the easy thing to do, because it was a really dark period. But I was like : wtf, again ? I already fixed that some years ago with a lot of money given to a child psychologist. (Divorce was at 5, and stutter started at 12) And actually I really did already overcomed that. These therapists focusing on "making peace with my childhood", didn't worked too, because... it was not the problem this time. I met one good psychologist one day. She told me for the first time : we will not focus on your parent's divorce over again. I think there is not one reason. It's a multitude of reason. And I felt relieved. For the first times I knew that it was true. In my family, we have a genetic predominance for stuttering (my dad and his mom stuttered when they were teenagers). And I think it's that : problems have accumulated, and mixed togetherw until they reached a certain point, and triggered the stutter predominance. Now I am trying to work on it the better than I can. Even if it's a taboo in my family, I know that even if the root cause here seems at the beginning "genetic", it can be cured (my dad and my grand-mother don't stutter anymore)
