Depends on the level of stuttering, I personally stutter only when I'm not confident, or anxious, and the thing is I am always anxious haha😂 But I have seen people with such a severe stutter,they can't even get a word out, it seriously affects them, and people DO care as they definitely are gonna say something. I feel stuttering is more in line with conditions like anxiety, hypertension,depression,ADHD rather than literal disabilities like deaf, colour blindness etc. The thought that something can be cured, with constant practice, and therapy, isn't a "true" disability, is what gives me confidence to speak better.
