Oh major prayers are coming your way.
Having a relaxed attitude will help you think more clearly. Maybe on the way there put on some soothing music and unwind, meditate. Its the best way.
If I am nervous at an interview OMG all I do is talk 100 mph. AND I don't remember what I've said. Those jobs I never get. I've learned a valuable lesson thru the years thats for sure.
You will do wonderful Liz
