Rachel, you do feel kinda all over the place, I'm sorry for your losses and hardships. And that said, I don't think how you got to where you are is the point. You said initially that you changed your mind when you fell for a straight woman. I can certainly understand the conflict between wanting to be the person who can fill a role for others and I can't pass on what decided you on this fork in your path.
Under WPATH 7 hrt is effectively informed consent, however if you've changed your decision on surgery I can well imagine your medical team putting some extra scrutiny. I don't think it's fair to blame them for allowing you to transition, lots of us who do have one stripe or another of PTSD. And then I rarely focus on blame, I prefer to think about how to get from A to B or in your case B to A.
Fortunately hormones can be provided exogenously, I initially would have preferred to keep a testicle as a source of testosterone, my surgeon said that while yes that's been done, she's not willing because it wouldn't have support structure and that if post op I need testosterone for whatever reason, exogenous is fine.
Hell, come to it I'd have preferred to be hermaphroditic, however I also understand that that's not something available from surgery and also where I've come to in a year & 1/3 of RLE is a solid realization that among the options, yes I could survive as a male endowed feminine person but ultimately I'd want to be binary female. I know may feel differently after GCS because you just can't keep all other elements equal.
I'm sorry you're going through this and am sending you my best wishes for peace and happiness.
