Sudden inability to say first name.

Sudden inability to say first name. I am a 24F in my last year of law school. I have managed my stutter to the point where I am able to get through school, however in the past couple months I have suddenly been unable to say my first name, whether it be during introductions, ordering food, etc. I have no idea how this happened. The first time was during an introduction in front of my class at the beginning of this semester and now whenever I have to say my first name I almost can’t get it out. I have never had trouble with my name in my entire life and it was been a nightmare, it makes me not even want to leave my house. Has this happened to anyone else?
