Getting a performance piece ready and I'm terrified

I have such anxiety over this it's not even funny. Normally I love to perform, my imperfections and all. I find it energizing and so empowering. But this time I'm taking a BIIIIIIIIG step away from my usual style in every way, and it's horrifying. Urgh. Double urgh. !!!!!  What was I thinking when I had this bright idea lol
