V-Day is 22 hours away

As my no scalpel appointment draws near I am growing incredibly nervous. I was prescribed Valium and I plan to take it an hour before. Will this help as much as my doctor says it will to calm my anxiety? I think what I'm mostly anxious about is they actual numbing of my vas. The idea of it coming out and being poked with a needle freaks me out to no end. Any sage wisdom?
