http://kelsbels27.livejournal.com/ I really have to agree with you when you say that acting is extremely hard. But i know that once your up on stage and you try your best the nerves will go away and you will feel good about yourself after doing it.
Im sure you will do an extremely good job, a piece of advice, revising your lines will boost your confidence so it doesn't look like your reading it for the first time. Goodluck and i will be looking forward to watching your play.
