Yes! I personally don’t stutter all that often but I can block really hard in certain situations. It’s always on my mind 24/7 like you mentioned - that I don’t want people to find out and see me struggling to say a word. However, when my wife eventually found out and saw me struggle, she literally did not care. The disparity between how I treated it in my mind (and still do) compared to others is striking. We treat it as almost life/death because it’s so hard for us but it doesn’t appear that way on the outside.
