I'm going to Court soon and I am impossibly shy. How do I cope on the stand?

I’m due in Court reasonably soon. I was attacked and will need to take the stand for statements and what not. I’m fine with seeing the attacker again, but the whole courtroom, especially the barristers and judge, is too much. I do find all the formal clothing, gowns and wigs quite intimidating.

However, I am determined to attend in person and will not let my shyness stop the proceedings. Any Court specific advice? Anyone been to Court before with similar problems?
