Your friend's story and mine are similar. I was all set to have a natural, vaginal delivery. It never entered my mind I would end up a C. My mom had three huge babies, my sister had four;three of which were home births (I attended two).
I ended up with such a horrible experience and they had to anesthetize me also. The entire time my baby is being taken from me, I was on some horrible nightmare-trippin', anethesia-induced freak show. I actually thought I was dying in while I was under and would never see my baby.
They let me breastfeed right away but I honestly remember very little - I was still so high. Not at all what I had dreamed my birth experience would be. Most people didn't really understand my disappointment and it was truly a feeling of sadness, feelings of inadequacy, loss of that first wonderful experience, etc. Most people do say, "well, the most important part is that he's healthy." Duh. Yeah - that goes without saying.
Still, it would be nice to have heard...."I can't imagine what you must be feeling but I know I would feel sad and disappointed that I did not get to experience the birth and joy of seeing my baby come in the world. I know it must be really hard to go through that. If you ever want to vent or just have a good cry about it, I'm here."She may be stoic about it but at least she knows you undestand the grief she is experiencing.
Best wishes!
