I was an ally™️ before I transitioned so already fairly invested and educated on the trans community, I spent a lot of my time advocating for us. So I knew that what I felt was gender euphoria when one day I saw a boys vs girls meme and imagined myself as a woman in a way I guess I never had before. It was pretty wild because I knew enough about the trans community to pretty accurately appreciate how much the trajectory of my life had changed in that moment.
It made a lot of things line up as well. One time I told an old therapist that the discomfort I had with my body felt a lot like what trans people described as gender dysphoria but "I didn't want to appropriate their experiences" 🤦♀️. I don't know how I didn't put two and two together there, but my therapist must have been asleep at the wheel jfc. I also remembered being a kid and reading Calvin and Hobbes and thinking I'd set their transmogrifier to girl and be a girl and getting a fuzzy feeling from that. Few other things too.
