How have ladies with anxiety handled c-sections?

Liz
I'm scheduled for a c-section next Wednesday (!) I am wildly excited but as the day gets closer, I'm thinking about logistics and how I'll actually handle myself/avoid a massive panic attack? A coworker told me she thought she had stopped breathing after they gave her a spinal block. Which resulted in horrible panic. That, of course, got me freaking out. Anyone have tips? Positive experiences? How have you handled laying there, being awake, and being cut open?!
