I'm sorry that you feel this way OP, it really is absolutely understandable.
I had my DS (only child) via a planned C-section under general anaesthetic as I had a brain haemorrhage at the end of my pregnancy.
For full disclosure at the time I did feel some relief about the plan for his birth as I was terrified and felt inadequate. I guess also the fact that it was all planned and arranged in advance rather than done as an emergency was helpful.
However, I found the moments prior to being given the GA scary and I felt extremely vulnerable. The room was packed with medics and no one other than the main surgeon and anaesthetist introduced themselves. I wasn't able to have my DP with me.
I was seated on the operating table and it was tipped back and my gown removed and replaced with a bit of sheet which left me feeling very exposed. They forgot to tip the bed as well as lie me flat so I began to feel dizzy and someone got a bollocking about it which was unpleasant.
They told me that whilst I was being given the GA someone would be applying pressure to my neck which might make me feel panicky but was important. I just nodded as it wasn't the time for questions but that was really difficult and confusing.
I also had to be under GA for the shortest time possible before DS was taken out, and I totally accept that this was a priority. But to achieve this my gown was removed, upper pubic shaved and cleaned, legs hooked out of the way, catheter inserted etc.. I felt like a piece of meat, I was frightened and the room was full of people.
There seemed to be a lot of people looking at me, and all sorts of discussions going on but none was talking to me.
I was (and still am) sad that I first met DS several hours after his birth through a haze of post anaesthetic and morphine. I wasn't able to process what had happened, didn't realise he was my baby and was very confused.
The next 36 hours were a morphine filled haze too and I wasn't lucid enough to bond with him despite him being left alongside me.
DS is now almost 16. I still feel sad and guilty about his birth. I wish I'd been able to meet him with a rush of love and nurtured him from the very start. I also feel some anger and frustration towards the medics in that room and because I wish I'd been better informed and prepared in advance.
But 16 years on it is now just one of those sad parts of life which I guess everyone experiences at times. I've tried not to bury the sadness, or try to fix it as it is a genuine and understandable emotion.
The anger is probably justified too. But I also feel grateful as DS was delivered safely and that was always the most important thing.
