Yes, and no:
Again, be me, your sympathetic but otherwise bog standard corporate executive!
What shall I tell my clients? "Well, X is brilliant, they're just too afraid of you to face you directly (from what I am being told, that is, they're too afraid to face me, too!)"? "X has successfully navigated the horror that is a graduate accessment process, so we hold out great hopes for X!"?
Look, I hate to be Debbie Downer, but: I'm currently the boss of the boss of several youngsters who can't stomach a (relatively junior, at that) client. My call, every single time, has been "then get the hell rid of them! I still spend a sleeplessness night ahead of every actually important meeting - because I'm anxious, too - but: I WILL EVENTUALLY DO IT! Because that's what I'm being paid to do!"
I'm not unempathetic - but if you're going to be so complicated that the standard job requirements cannot be asked of you then you might, just might, not have any business being in the job!
I will spend hours upon hours gently coaching you, trying to teach you, attempting to remove your fear. But there is only so much I can do. I'm a corporate executive, not a trained psychotherapist!
