I'm a Camera Shy Bride, How do I Overcome my Fears Before my Big Day?

I have a huge fear of being on the other side of a camera, by that I mean the side that's in the photographs! My second shooter Theo will testify, when he wants to test out the light in a room I very quickly find a very pressing job in a room far, far away and he has to persuade an unwitting wedding co-ordinator or handy vase of flowers to help him out. Every now and then, when I don't think quickly enough he gets to work with the back of my head! (poor guy!)
