I need help...please?

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

Tell yourself anda 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 bernyanyi think that your a bintang and the ppl in the crowd is your fan :P

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