I am really greatful because I looked up the internet ,it says stuttering can be cured but not 100%. But in my case I don’t even a word for about 4 months which means I am 100% cured. No matter what my emotion is I don’t stutter. So I tested myself to go the random group of people and talk random topics but I didn’t stutter or stammer. I called to random friends too to ask how their day is going. I think I main thing is our inner voice and actual voice have to be the exact same. When our inner voice try to speak the way our actual body can’t speak, that is when we stutter.
