Why Does My Stuttering Get Worse Around People but Not When I’m Alone?

Why Does My Stuttering Get Worse Around People but Not When I’m Alone? I have noticed something about my stuttering and wanted to check if others experience the same. When I’m alone, I can talk freely without stuttering. But as soon as I’m around people or anyone else, I shutter I also found that my trigger words usually have vowels. So, for example, if I have a presentation in class, I try to avoid those words sometimes I even use ChatGPT to help me rewrite sentences without vowels to make it easier so that I can present easily So here’s my question: can you all talk freely without stuttering when you’re alone? Or is it different for everyone?
