OP, I am so sorry you had a dreadful experience. I did too, but it was very different.
Dd1 was 36weeks when delivered by emerg Csection under GA. I had pre-eclampsia. I was induced, but she became distressed & we needed to get her out. No time for epidural etc.
She spent 2 days in SCBU. During which time I got to see her for 10minutes. That was it, for 48 hours. It was gut wrenching!
I was unable to bf. I had no help to get her to latch on, I didn't know that premmies found latching on difficult & no one had time to help. I ended up giving her bottles as she just needed food!
I really suffered in the year after her birth. Suffered because I wasn't the first to hold her, to feed her, to dress her. I had no idea if she cried when she was born. It really does mess with your head.
After a while I sent a huge email to a friend to tell her all about it. I told her how I felt, how horrible I felt about missing her first days etc. How I felt I had failed because she was early & she had to be pulled from me, not delivered by me.
She said, amoung other things
"While I have no idea of how important those things are you mentioned [she had no children at that time] you have years ahead of you now with dd, I am sure that there are many more important things that will come your way & you will be involved in. You have a whole lifetime together.
As for your scar, that is your daughter's door into this world, be proud of it, it is you & it is her, a vital part of her life.
You gave life, you gave birth. Which ever way you see it, you are the most important person in her life, no one gave her what you could, what you did. Let them have the first nappy change, you have all the rest"
It was those words that turned me around, made me realise that some things, whilest very important to me, couldn't be fixed/changed.
Living under that cloud stopped me from enjoying my baby & I really had to decide to let that part of our lives go, so I could enjoy the rest.
I do know it is hard, and I do know it is important, but are you going to let it overshadow the rest of your life?
What I am trying to say, hopefully in the nicest way, is that sometimes, you just have to let it go.
Good Luck!
