Killer, do you have a good friend who can go with you to the hearing? I was a wreck before every court hearing I had to go to, and that actually helped. My friend wasn't allowed in the court room every time, but just having someone there holding my hand before and going to the bathroom with me and waiting for me outside afterwards was really, really helpful.
And it really is difficult. I don't know your entire history, but having to face someone in the court room who has been abusive to you is incredibly stressful. Think of it this way, though -- if you are nervous around him, that's something the judge needs to see. (((hugs)))
