YES! It was so bad for me that I couldn’t even say my own name. One time I was at a company lunch with bunch of higher ups, at my first job. When it came for me to introduce myself I just went “uh uh uh”. A year later I was at the same company working for a different executive. After a couple months, he called me into his office and asked me if I have a stuttering problem. I was taken aback since no one asked me in a long time. He then told me that, he use to have a major stuttering problem too. Hearing that, really comforted and assured me!
