I have no clue if what I'm going to say will be helpful or not, so I applogise in advance?
I guess you need to learn to feel comfortable with yourself, around others. Try practising in front of mirrors?
I used to do that and coming up to my final performance, whenever I had free time at home, I'd rehearse till I knew everything back to front and front to back. That way I'd know that if I slipped up, it wouldn't be because I forgot my lines and it made it easier to rehearse.
Also if you could rehearse on where ever you're going to be performing it, you would feel more comfortable with the "stage" and it would make the real things feel like not so much of a big deal.
If you can, try and relate what you're saying to yourself or someone you know and that way, it is more meaningful to you. All the pieces I couldn't do that in, I couldn't act so well because it just didn't "click" with me.
I was the quietest person in my drama class (well I guess I still am). I didn't real break out of my shell until my last performance and that took so much work becoming comfortable with myself. Also, I was comfortable with the people around me - it was my favourite group to work with because I got the choice and it didn't take so long to become comfortable with them as it did with others because I felt they wouldn't laugh at me or judge me (though in truth, most people in my class wouldn't have).
My motto in life is "Fake it till you make it" - If you don't feel you can do something, that you do it anyway and pretend you can. If you pretend you feel confident and act confidently (walking straighter etc), you'll eventually feel more comfortable with yourself and it wont be so hard around others.
What grade are you on in the written part?
(Sorry again for what I'm pretty sure is unstructured, probably unhelpful, weird ramblings
)
