Yeah, this seems super common. When I started HRT my dysphoria evaporated, too! That triggered a few "bounces" where I'd think I wasn't trans anymore, and then realize that no, I really am, and back and forth and back and forth. So frustrating! But that's gone now. I love my tiny boobs!
Of course, now that I'm about to come out at work, I'm going through the same thing all over again. I've been gradually presenting more and more femme, and I'm pretty happy with where I'm at... do I need to come out? Bah.
