I am just like you. Mild enough that people think i’m nervous, but still bad enough to have traumatic experiences in crucial situations. When I’m tense or overthink before I have to talk it comes out terrible. I have a nice voice though, would work amazingly in broadcast or whatever. The irony. I always say I have useless talents that I can’t use in real life because I stutter. Oh well. It helps to write down a list of what you’re grateful for and focus on what you can actually do. Good luck. It gets better
