The moment you stop blaming your stutter for your shortcomings and downfalls the sooner you will feel so much better about yourself. In my interview I stuttered like a mad man and do any time I talk to my superiors but they already have me leading teams of people in just 4 months of working there. No one is forcing you into isolation, I know what the anxiety around it feels like I feel it all the time, but it’s not because people don’t want you around or don’t respect you or whatever it is. Most people have never met someone who actually stuttered and it can be confusing. Whoever you’re working with or for, the people around you will start to learn we just got a misfire in the vocal box.
