I actually noticed recently that my mindset has changed drastically since before I started T. I would say I felt really similar to you. I was worried that my height, amongst other things, would be a big issue for me. I found myself watching TV, and seeing guys thinking "OK I kinda look like him...oh, Daniel Radcliffe is my height and people think he is attractive, Seth Green is my height...that guy has a face like mine...oh look at these guys walking about, they are my height." Now, 3 years on T, I see these guys and those thoughts don't even cross my mind anymore. I'm comfortable with myself and I never feel jealous of other guys anymore. No one sees me as a woman. I have all the changes I can possibly get from T - I have a full beard, I'm hairy, fat changes, voice is deep. The guys see me as just another dude, and I see them as just another dude. If a girl rejects me for my height, so be it, I'll find one shorter than me lol. Sometimes I do feel frustrated about my pre-op condition, but I just view it as something I have to be more private and guarded about. For example, when I use the men's changing room, I can't be out in the open. The guys I work with just think I'm embarrassed because I'm sort of fat. And hey it sucks, but one of the girls I support needs me to be there in the changing room with her to help her change into her bathing suit. So what's the big deal if I have to find a private stall to change in? At least I don't have some dude I barely know taking my clothes off in the family room because I can't do it myself. It's just a temporary accommodation I need to make into my life.
I guess what I'm trying to get at is that it does get easier. Once you're on T long enough, and you no longer need to tell people you are trans, you're accepted into the guy's circle and you reach a point where you don't have to compare yourself anymore. Being short, and being pre-op (which isn't forever) become just a part of the guy you are.
