When did y’all notice you had a stutter?

When did y’all notice you had a stutter? As a kid I always had a stutter but I never noticed it until I was in high school. As I’m sure all of you know as a teenager you tend to care about what other people think of you. I became super ashamed of it and still am almost a decade later. I have a lot of hatred and rage towards it because it has ruined my life. It’s the one thing holding me back from conquering the world.
