its the first 3 options for me. whenever i have a block while talking to someone, theyd just stare at me weirdly and it would make me feel very conscious about how i speak. when i have a serious block, i could feel my chest constricting and if i were to manage to get the word out, it'd come out breathlessly if yk what i mean. and the frustration part comes from the fact that speaking is essential in our lives, regardless of whether its something as small as calling someone over the phone or something as big as giving a presentation in a meeting. a disability in something thats crucial in our lives often frustrates me, it makes me wonder how my life would be different if i werent a stutterer.
