I don't know about my dysphoria getting worse, but my body insecurities in general totally have. Before, I literally didn't care what I looked like or whether I was attractive, because the person in the mirror wasn't remotely "me." Now that I can actually see myself in my reflection, I notice the fact that certain bits are overweight, that my skin isn't perfect, etc. And I actually care now, because it no longer feels like I'm hidden under a mask.
Like others have said, the focus of my dysphoria shifted too. My voice was a huge thing before. Now that it's dropped, I'm a lot more worried about my height, bone structure, etc., that T cant fix and I never worried about much previously.
