I have the same thing and struggle to say my name. For mobile ordering, I use another name and for some reason I don’t stutter but when it comes to my name I can’t say it 70% of the time. Over the years, I’ve been practicing better ways to say it and it’s helps if I say something else and transition to my name. Like Hi I’m B—. Beautiful day today, I’m B-. And just anything. I also have been struggling to find friends but going out of my comfort zone and joining a group has helped me practice saying my name more.
