Confident on stage but not life?

I understand how you feel. I'm 24 and have been onstage since I was 5 and have been struggled with Generalized Anxiety Disorder since I was 8. What makes sense to me is that I'm confident onstage because it gives me focus and it's something that I love to do. I know what is expected of me and I know what I have to do to do well. In life, you aren't playing a role, you are playing yourself. And you aren't given your marks, your lines, or your direction in life. You are the one who has to "direct" yourself, which is difficult, hence, the anxiety. Also, know that if you continue a life in the theatre, you will continue to deal with people who doubt and tell you how to do your craft. Your teacher, for some reason, feels he/she knows what you are capable of more than you do. That's just her/his opinion; don't let it discourage you. If anything, let it motivate you to do what you love and "prove them wrong" if you will. And to the person who said "you don't seem the actor type": What is the actor type? There are so many different kinds of people who are drawn to be onstage. There isn't one defined type of person you must be to be onstage. I'll be honest: I constantly doubt myself as a singer and actor. The trick is not to let it get the best of you, but let it motivate you to keep working and to keep getting better. Turn the doubt into inspiration. I hope this makes sense and helps somewhat. If you want to talk more about it, please add me as a friend and message me anytime :)

It definitely makes sense how you can be confident on stage and not so much off. I believe Shakespeare once said something along the lines of people are able to act more truly of themselves when wearing a mask. I don't get why that teacher told you you couldn't read out-loud, I don't think I've ever heard a teacher say you need to take acting classes in order to read out-loud. But don't let people put you down, they are bound to because it's become a thing in our society to scoff at those who want to pursue something in the arts just because there isn't a big profit margin for it. But if it's something that you love to do then please continue to do it. It would be a disservice to yourself and a disservice to everyone else if you stepped out of the spotlight for fear of judgement. I can't remember who said it but I remember someone once saying that if you don't have any enemies/critics in your lives then you accomplished nothing. I'm not sure how to deal with the anxiety that you feel but I know that I get the worst stage fright and am a pretty introverted person, but when I had to do recitals and concerts I would feel so much more confident. I would say wait til high school to do drama class and you should join drama club and meet people there. For the most part most drama kids I've known are pretty introverted and outgoing so perhaps they would make you feel more comfortable to open up more and it's a good way to meet friends.

shakespear said " the world is a stage and the people are mearly actors" soooo whats the difference ?

Personally, I think it is COMPLETELY normal to be confident on stage but not in life. On stage, you are playing a character. In life, you are playing yourself. Just as it is so much easier to give someone else advice than it is to give yourself advice, it is so much easier to play someone else's part than to play your own. When you are acting, you are confident because you know your part and how to play it. In life, we don't always know our part or how to play it, so we sometimes lack confidence.
