Damn, this is so relatable. I have a mild to moderate block that tends to heighten in scenarios that make me nervous or second guess my speech (aka taking food to a table and saying the names of said dishes). To most people, I don't have a speech impediment. My girlfriend of 3.5 years has admitted she would not have noticed had I not told her, and my sister only picks it up because I have told her and I'm not afraid to block in front of her. Nobody else knows. I've actually been meaning to tell my close mates as I need their advice on whether or not I should pursue acting as a career choice. It's going to make the discussion very weird as to this point they've had no idea. I've spent all my teenage and adult life thusfar hiding something I was born with. It's time to not be ashamed of the hand we were dealt; let's play it instead.
