I am 6'2" and my biggest hangups pertain to my height, no doubt, so I totally understand how you must be feeling. In fact, fear of the attention my height might attract paralyzed me. It was one of the main reasons I stuck it out in the male role for so long, even as it became utterly unbearable.
Enduring that unbelievable emotional tumult living in the wrong role earned me only regret because once I started transitioning, I finally found my happiness. Realizing that I could have been happy instead of miserable for all those years is very annoying for me now. I try to not think about it.
For me, I got over the hangups simply by learning to be proud of exactly who I am. That pride allows me to not fear being read or whatever. That doesn't mean I go around shouting my past to the rooftops (I don't tell anybody that didn't already know me.. ever) it just means that I will never be ashamed about the reality of my life.
Yes, transition takes fortitude, but guess what? I am not a strong person, like.. at all. To this very day I still can't believe I found the strength to get through all of this. If I could do it, I know you can.
