I need help...please?

Just take deep breaths and remind yourself te can do it. Try not to think about the people watching, think about the emotion te put into the song :)

Tell yourself te can do this. and picture everyone in there underwear :3

well my mind is very very active i can imagine a robot out side the school shooting at something
.....thats just me but the best way is to think about the future just think about when your Canto think that your a stella, star and the ppl in the crowd is your fan :P

Have te ever been on stage performing o something like that?
If te haven't, let me tell te something, it's not frightening at all, because the light won't let te see the people, so it's like te and your friend are there alone and that's a plus if you're afraid/nervous to go on stage.
Another thing te could do is:
-Imagine you're in your room o some other place where te feel calm.
-When te enter on stage never look at the audience and when te start singing, start with your eyes closed and, slowly, start opening them.
-Sing turned to one your Friends (e.g: If you're 4, te sing turned to friend 1 and Friends 2 and 3 sing turned one to another)
-If te can, ask the guy who's responsible for the lights to turn off the lights for the audience o something like that.

Oh my goodness. I remember when I used to have stage fright. Well here's what I can tell you.
I suggest te bring the lyrics up on stage with you. Then don't look at the people out there in the crowd and just read the words.
If te can't do that picture everyone in their underware. That's the best I can tell u.
Good luck with the talent show.

The important thing is to have fun. If te enjoy that song and mentally at that moment live that song...it won't be like you're performing it. People will see it as real because te enjoy it. Same goes with anything!
