Yup same here. Its not "damaged" its rewired. I had a mild stutter but as I grow up it got worse because of social anxiety. That doesn't mean my speech mechanisms are damaged. Its just the brain rewired to behave in those situations. I had to do speeches every once in a while in my class. So I was anxious af. I'm sweating, shaking and I am almost mute because of the speech blocks. The worst part is I see people laugh about it. I mean its a thing that I have born with therefore I can't "change it". Those moments made my stutter worse than ever. People could be born with severe stutter but for me its mostly the social anxiety.
