I don’t have much dysphoria but I had a LOT in 7th grade. But that’s probably because I’ve never really been a boy. When I was young, I was very gender non-conforming because I didn’t want to be masculine (but I didn’t understand it back then). Later on, I grew my hair out. When I looked in the mirror, a feminine face stared back. Sometimes I felt like it was a strangers face, but most of the time it was a feminine face. Because I saw myself as feminine, I never really felt dysphoria much. But, since you’re curious, the voice in the back of my head that screamed “YOU ARE NOT A BOY” got it's voice in first or second grade. I can’t pinpoint an exact time, because it started like those songs that “fade in;” quiet and slowly getting louder.
