stage fright
Once you're on stage, the stage fright will go away.
— Lust, Caution (2007)
J'ai trop le trac pour manger quoi que ce soit.
I'm too nervous to eat anything.
La jeune mariée arrive, elle rougit, elle est timide, elle a le trac.
The young bride arrives; she is blushing, shy, and nervous.
