How do i get my self-esteem back?

Question:

How do i get my self-esteem back?

next year, i'm going into junior high (i no, i'm kinda young for Yahoo answers), and i think i have a wonderful voice. But when i sing to my friends, i tell them to critisize me as hard as they can without swearing. Then i sing and they tell all the stuff, but i act like I can handle it but i can't. One of the problems is that i go too up and down, too jerky, ya no. My homeroom teacher (who is also kinda, not really good at music, but still has a good sense of it) tells the class that most people can't stay on key when they sing loud, but i'm the opposite of that.

Basically, going into junior high, my bro told me that i could audition into the advanced choir in my junior high and i have to audition on Monday, after school, but my bro says that out of 10 people that auditioned so far, only 1 made it in. i am sooo scared, but when i sing in front of crowds, i at first start to feel like i need to throw up, but when i get up there, it feels so good.

By the way, i'm more of a soloist

Imagine yourself as a broadway star, dont care what people think, im fifteen and junior high ruined my self esteem too, im still getting it back, but dont care trust me its better, if you think you sing well then that's all that matters, and why not get lessons? Also dont tell them to critacize you, tell them to tell you the good things not the bad
