Bro honestly you sound like me when you explained that in detail. Because I’ve been telling people that same thing and they never understood what I was trying to say. It’s like, when I’m around my family, they already know I stutter, but it’s like even when I try to calm down and speak fluently I still can’t when I’m around them. But around strangers or acquaintances, they can’t even tell I have a stutter. But I’ve noticed when they can’t tell it’s because I’m in a masked version of myself. Idk if that makes sense. It’s like I’m not showing who I really am due to fear of judgment. I’ve had a bad history and reactions to my stutter when I was younger. So that adds to why in a way. It sounds like you because very analytical about it tho. That’s the same way I am. I’m not sure if that’s the same case with you though 🤷🏽
