preparing for an induction

Brooke
My due date was on June 29th, but I have an induction date set for July 6th... Currently I'm 4.5cm dilated and pretty much completely thinned out; the doctor said when she checked me the water bag was right there. I've tried everything to jump start labor myself, but nothing is working :/ 
I'm getting super nervous about the thought of being induced and also thinking what if my due date is wrong and that's why baby isn't here yet. I really don't know what to expect. Is there anything I can do to really prepare myself?
