Hint:

Don't "look" at the microphone ~
Just focus on your Host and cary on a 'conversation' with him.

First time I had to do an on-camera TV interview after a fire - the News Girl noticed I was so nervous I could hardly stand up!
Her advice was to focus on Her Face and to NEVER look at the camera or her microphone...
Managed to get through the interview without throwing up!

You'll do fine!
