I totally feel with you on this one. The amount of times iv had people look at me funny when I’m not able to say my name. Saying your name is the one word we cannot change. But I believe a lot of the anxiety is built around saying it and also there could be some PTSD from memories of people mocking you when ur not able to say it. What I’d suggest to do is work on your anxiety and perhaps even start CBT therapy. If u can’t afford it there’s heaps of free recourses online that help you discover and unpack the root of the anxiety. Remember that no one’s speech is perfect. Every single person stammers or stutters from time to time the only difference when it comes to our names is that we have alot of shame around it
