Baby almost here?

I'm very nervious that something might go wrong, this is my forth pregnancy, but i lost all four babys. I had twin boys at 28 weeks they died after birth, I also had two miscarrages. So no wonder why im a nervious reck. I have scudule c-section about a week and 3 days I cant wait to see my baby. But i dont want to get too excited because something might go wrong. what can I do to control my anxiety? and what will the c-section be like? when i had one for my twins it was emergency so it was caotic.I want to hold on my son after birth, is this possible?
