Take a deep breath. It should be fine as long as you know your material. Go over it again until you feel confident. Look in the mirror or give the presentation to someone and have them critique it. Other than that, I don't know. I'd make sure I knew, give it to a friend or family member, then relax and listen to music or go for a walk or hike.
