The dream outcome to delivery is a healthy baby and a healthy mother. A healthy baby on its own does not equate to a dream birth. The birth precedes the arrival of that healthy baby and can be a traumatic and debilitating experience. No women do not have to sweep their feelings away until they're hidden any more than somebody who has a perfectly happy life should just cheer the fuck up if they suffer from anxiety or depression or somebody else should just stop with the dithering and messing about if they have OCD.
I experienced birth trauma. I had a long delivery, every intervention going, emergency surgery, a haemorrhage, transfusions and it was debilitating. I had PTSD, PND and it took 2 and a half years for somebody to refer me for specialist intervention. I cried for 2 years. I couldn't look at my body or in a mirror. I had flashbacks and nightmares. I hated myself and thought I would never feel joy. If I hadn't tried to bury it all, if I hadn't listened to the absolute ghouls who insisted a healthy baby was all that mattered, I might have been honest. I might have sought help. I might not have sacrificed 2 years of my life. And I do matter. As the guardian of the that baby, I had every right to speak about my health and my life and my feelings.
OP, it's early days. Do speak up about your feelings to a health visitor. Ask about a debrief. You are allowed to feel this way.
We spend so much time thinking that we can "achieve" things that are out of our control. "I got my dream birth", "we got our first choice school" and on and on through feeding choices and academic outcomes. So many things bandied around about achieving and deserving where motherhood is concerned. All failing to recognise that there are so many things out of our control. What we deserve is equality and to be treated according to our own circumstances and feelings, listened to and supported on the path upon which we find ourselves.
I had a second emcs btw and it was the happiest of processes. No less medical and not the home birth I'd tried for again, but I was well supported, listened to and free from the judgment of other people.
Congratulations on your baby. Things will get better re the birth of you are allowed to speak about it, rationalise it and work through your feelings.
My big girl is 17 and now, it was just the day we met. For a time, it was a black hole into which my mental health was being subsumed.
