How can i become more outgoing with more self-esteem?

Hi everyone... I am so nervous because I am going to be in High School theatre this year! And I was already last year when I was a sophmore but I was so nervous, I cried at home after play practice because in a few days we would be doing our actual play...

at another school in front of judges... I always feel nervous talking to someone I don't know or in front of people I don't know , but when I'm with family and friends I am like really talkative and I make my friends laugh all the time, but I just am self concious I guess of how I look and seem to other people... (mainly other classmates) My theatre teacher is awesome! She knows I am insecure because she approached me asking why I was... She said to me: You are self concious aren't you? But I don't know why you would be you a are very pretty and nice girl. I felt embarrassed but happy at the same time, but I was still nervous about the play that I almost quit and let down my theatre class mates! I felt so horrible... but the thing is I love acting and that kind of stuff, I just get REALLY REALLY NERVOUS. Well my question is: How can I become more outgoing toward people and how can I have more self-esteem for myself?! Thanks and please help me out here! I have been stressing over this for the entire summer!!!!! And thats no fun! Thanks for your time!

well im still working on my self esteeme and such but i guess u just have to learn to love urslef. u cant really change the way u r and from what i see of ur pic u do look vry pretty. and i kno how u feel onstage, i was super nervous my first time on stage, especially my first time in front of judges. but it usually helps that u cant see ne one and u can kinda block it out. just focus all your energy and think only about ur scene, lines, body language, ect and try to forget everything else. and practice on stage always helps. its perfectly normal to be nervous but hopefully it will pass.
i hope that helps even a little.. :]

Chels, you never told me these things? Not that far at least, u never told me u considered quitting!!!

Yeah I wanted to quit but I knew I wouldn't! lol, I don't think that will happen this year though! THANKS GUYS! XOXO

sorry cant anwser trying to do the same
