Interesting that in her 3 posts, the OP has said she didn't feel listened to.
And yet here we are, another 10 pages in from her last post, shouting at each other, not even talking about her or offering advice that might help.
Yes AIBU is savage. But maybe it wasn't just her partner and doctors who didn't listen to her?
Perhaps we are all guilty of being so ager to argue our points that we forget there is a real family at the heart of this. Some of the theoretical arguments cited are ridiculous.
The Ops experience is her experience. Telling her she could, should, or would have felt better if... won't change it. Its done.
What's needed is helping her understand what, happened, why, who was at fault and what, if anything she wants to do about with regards to the entire experience. Clinical, relationship, counselling.
It is not our place to tell her what she must do, only direct to what help is available, show support and encouragement.
Jeez, haven't you read that she's had enough of people overriding her wishes already? Give her some space to reflect and decide.
