I'm covert, but I'm honestly way too hard on myself, focusing on every little "mistake" I make in conversation. I just elongate my sounds and pause and block a lot which I guess most people chalk up to nervousness, but I ruminate on these instances of "not perfect speech." Due to this, I don't really talk to anyone outside of my friend group or anyone of authority like teachers. I bet people wouldn't even know I stuttered unless I brought it up myself. Home is the only place where I can feel free because I couldn't give less of a shit about how I talk there.
