Hi Emma
Have you got a good GP? because a good old chat to him or her can really help. I only suggest this because it seems everyone else is getting your nerves quite high and this is not good for your BP. Let them know how nervous you are getting with all the different options that may happen (induction/C-section) and how you are not sleeping well either.

It was different for me because when I was told I was to go in the next day for induction I was quite excited as I knew I would be meeting my little girl the next day! I did find out all the information about induction from the midwife who did our prenatal classes so I knew what was what but I went into that labour room with a clear head on how MY birthing experience would be, because it was mine and noone elses.

Please take care of yourself and let yourself enjoy this time and the only other advice I can give is that whatever birth process you go through, it is the most powerful and rewarding moment of your life, take it with pride
