One of the things really struggled with for a long was creating a self-fulfilling prophecy. I'm not saying this is what you were doing. I don't know your situation. But for me, even though I told them I stuttered at the start, I was sometimes apologetic about it too. I was so nervous that they were judging my stutter or what they were thinking about it, that I became VERY nervous/anxious. In hindsight, I think a lot of people were aware I was anxious, and responded accordingly. At the time, I thought they were assuming I was anxious because i was stuttering. But now I think they assumed I was anxious because I WAS anxious. I was just anxious not to stutter. Now that I stutter more confidently, I rarely have that same dynamic. I do acknowledge that it takes time to foster that mindset and it's pretty challenging. it does still happen occasionally, but a lot less often than before. I appreciate the way that you tell them you stutter. I now usually say "I stutter when I speak, so let me know if you need me to clarify anything." This helps the listener see that I'm confident and it also makes it a lot less likely that they respond awkwardly to the disclosure lol
