C section Mamas! please respond!

I am having my first child via c section on Saturday morning and im getting so nervous. I looked up some videos on YouTube and now am extremely nervous and even a little scared. I cried the whole time watching them. 
Please if anyone can share their experiences as much as possible I would appreciate it.
Really just nervous about the procedure itself. 
How does it feel? What happens? I plan on calling my nurse tomorrow to ask some questions but would love to her your stories!
