Problematic Transgender Narratives: Grieving a Transitioning Loved One

I question- is the narrative of (especially) parents grieving a transitioning child problematic in general or just for me because that story doesn't at all resonate for me? I'm not sure if it's because I'm on the Autism Spectrum or because I'm agender and I needed my child to start me putting my own gender questioning into words- or any other number of things. I read things after my daughter told me that her assigned gender had been wrong that talked about gay and lesbian parents worrying about transgender children because of assumptions. I guess, I'm already so far from the mainstream that it never occurred to me to worry that my sexuality would be used as a reason why my child is transgender.
​
When I hear/read other parents speaking of mourning the lose of the child they thought they had, I have to keep my eye rolling to a minimum, keep my opinions to myself; I don't think most parents with newly out children are ready for the radical gender exploration in my head. First off, I don't think that grieving should ever be put on transgender/gender non-conforming people. Secondly, my child didn't die when she came out as transgender. I believe that my child is a whole person who doesn't exist to live out my dreams; at a PFLAG table when she came out, I said, “My only dream for my child is that she moves to an urban area where she's comfortable, and where I'm comfortable to visit.” I have no need to grieve the wonderful, intelligent, beautiful daughter who often sits next to me at SOGI (sexual orientation and gender identity) support meetings.
