Thanks so much for sharing this, Ely- now you know you aren't alone here! No apologies needed for refreshing this.
I know that my son also balks at the idea of performing. He has been able to learn to be brave in certain situations- he's learned to drive a car, for instance- so I wonder if there's a way to learn to overcome the insecurities and fears of performing. There has to be a desire to do it, of course.
