I had that too, I also just didn't know just how badly I wanted to be a girl until I met a really good friend who I learned was trans (and was also in the right state of mind not to immediately push her away), questioned my own gender, then experimented with she/her pronouns on myself and learned yup totally want to be a girl, really badly too. I also doubted myself a bit since I'd heard that you need dysphoria, but that didn't last long because I realized my chest dysphoria very soon after that.
