Model to assist self sabotaging

I would like some assistance with helping my daughter work thru the model. When she goes for an Audition she self sabotages herself before hand. Saying negative things to herself, such as; so & so is also auditioning, I am tired, I am not happy with myself at the moment, I am not feeling 100%, etc, etc. I think you may get it. I think working thru the model with her might help frame her thinking to be more positive. Any assistance would be greatly appreciated.
