Anyone starting to feel the anxiety yet?

Ti
It is getting closer and even though I am studying hypnobirth and I am planning a natural one at a birthing center, I am starting to lose my self confidence. I go to my midwife appointments and they all praise me over this choice and I am afraid of failing them. I love the idea of being relaxed and at peace, but what if this crap in my mind, the negative stuff, takes over? I guess I will admit I am afraid and lacking confidence in myself. I hope I can do this the way I truly want to!
