Anyone else get anxiety seeing people speak so effortlessly ??

Anyone else get anxiety seeing people speak so effortlessly ?? My stutter is pretty mild, but enough to where i’m very conscious of it. Sometimes when I watch others speak (especially those with high energy) without stuttering it gets me anxious. Especially when I try to imagine how i’d respond to it if they were speaking to me, and I get a block in my mind when trying to imagine a response. Like how the fuck are u able to speak without stuttering ??
