C-section worry!

Mama
Just been told that I need a c-section this time. Was hoping for another natural delivery, but due to complications for me last time, it's too big a risk. I am really freaking out. The thought of being awake makes me feel ill, but I'd like to be, as better for baby and husband can be there. Anyone in the same position? Or anyone had one previously who knows what it's like? I'm in the UK, not sure if the procedure/meds are the same elsewhere? x
