I relate to this so much, I also stutter with my name i can’t say dha, and my name is dhaval, you feel embarrassed when you can’t say your own name, it’s hard to live with that,I also feel so much stress at places where i have to give my name like hospitals, ticket booking, restaurent etc, It became humiliating, and Make the whole conversation weird. When somebody asks your name randomly and you can’t say,i still don’t know how to deal when that happens, It makes ourselves look stupid and kind of weird.
