I think I feel something very similar. I have this kind of weird lag where I experience something and then I can't figure out how I feel about it or what it was really like for a while. A few hours or a few days later I will finally have a reaction to it, but even then a big part of it is intellectually deciding how to feel instead of just knowing.
Since I've been on estrogen, my emotions are a lot stronger. Overall that's really nice, but it hasn't really fixed the detachment. Like the last couple of weeks have been pretty eventful for me, I met some new people and tried some new things. But it's still the same way it always has been. I figure out like the day after if I liked something or not. It makes functioning socially like a lot harder.
I do think a big part of this is just autism for me. But like the autism and the transness are linked in weird ways. Like do I mask for autism reasons or because I had to pretend to be a guy for a long time?
