You're not alone, several people here have shared that they experienced stuttering in adulthood, whether temporary or persistent. It's sad that your family didn't take it seriously, because what you went through is valid, even if it's poorly documented. I also developed a stutter as an adult (and it hasn't gone away), and I also have a brother who had developmental stuttering. I already had some vulnerability with language, since I dealt with selective mutism for a very long time. I also have neurodevelopmental conditions (autism, dyslexia). I recently read this article and related a lot to the cases discussed (adult-onset stuttering, progressive, similar in form to developmental stuttering): [https://www.researchgate.net/publication/45272408\_Similarities\_in\_speech\_and\_white\_matter\_characteristics\_in\_idiopathic\_developmental\_stuttering\_and\_adult-onset\_stuttering](https://www.researchgate.net/publication/45272408_Similarities_in_speech_and_white_matter_characteristics_in_idiopathic_developmental_stuttering_and_adult-onset_stuttering)
