yeps, depends if plates are fused yet, most likely not much change anymore if you are over 16. While if it was the opposite it might have made much more of a dramatic change to start hormones as the growth plate needs to seal faster rather than let open, they also seal later for the other way around.
So pretty much not much of change but the psychological "I want to start my life" eating you inside, and well, you not being so much of you and are blocked from maturing.
So I'd recommend to try start you life, if you start therapy it will also put you on the countdown for top tumor removal and bring changes sooner
