I think it's normal to be nervous. After all, our whole lives depend on some of this. I was a wreck the frist time I went out as Kate, but I got hold of myself, gathered up what little courage I could muster, said "show time!" and walked onto life's stage as shy, friendly Katherine. I'm so glad that I did, because eventually that led to me being able to be bold, brave Kate.
I think it helps to think of this in small steps. Don't look too far down the road - just look at what you can do now or do next and work on that.
