How can you stop getting so nervous and really red when singing for people I tried staying calm but that didnt work this is a serious problem I am facing and need some help please?

Aww! OK. A stagefright problem! Here's what I do and it works for me!:

1. Take few deep breaths.

2. Whisper to yourself a few Words of encouragment.

3. Believe in yourself.

4. When onstage, believe in your performance.
