Hii. I'm as short as you, and if it was not enough, I have a really childish face. I'm 18, and although in my school I haven't come out so everybody sees me as a girl, they always say that I look between 12-14 y/o. I'm even smaller than most of the girls in the whole school. I've gone to stores presenting as male and they have asked me where my parents are and if I'm lost or something (at least I passed, as a 12y/o boy but I passed...). So I think I can understand you.
Usually, I'm not that conscious about my height, but you see, my two younger sisters are in the same high school as I, they have the same age but one of them is taller than the other (although both of them are taller than me). The shorter one is almost my height, just a little bit taller, and when I get to see her at school, specially from far away... God, she looks so small and short and tiny and I think she looks kinda ridiculous standing next to taller people. And then I get depressed 'cause people often tell me that I look even smaller than her.
You know, I always had that complex of being short, even before knowing I'm trans. Since I was little, I always was the shorter in class, even in kindergarten. That, together with my social issues, made me grew into a really insecure and shy person, that never defends himself. Well, at least, it's been a long time since people bullied me. Instead, while I don't have a lot of friends 'cause I'm not a social person, nobody messes with me. Yeah, people usually calls me adorable an such but it's kinda ok. People know me in school because I've won several contests and I have an almost perfect grade. Even the people in the contests, the judges and such, recognized me several times.
So, as many people have said, height doesn't define you. It can be a nuisance (specially when you want to get something and it is high and it's out of reach), but well, it's something we can't change at all. And, as someone said before, you won't have to worry about competing with other guys that like to beat up other random guys to "prove" their "manliness".
I can relate with the thing that people sometimes don't take you seriously. Being short and having a baby face makes people think you're an innocent kid that can be easily fooled. I've learned to take that to my advantage. Maybe people will underestimate you, but the satisfaction of proving them wrong is big.
In my case, and taking into consideration that I'm gay, I sometimes come into terms with my height. Just like you said, I get times where I'm ok with it, and with the whole "adorable thing". "As long as I'm confortable being myself, then I shouldn't worry what other people think or say" I think. Then, there are times where I think that I will always be this small and that when I am 25 y/o I'll just look like a joke, like a child pretending to be an adult (not only because my appearance, I'm so unconfortable in social situations that I usually act weird and out-of-place, like... a lost child).
I know it sucks. Specially, by adding up dysphoria. But, think it this way: there are a lot of attractive and successful cis men that are (or were) pretty short. And the satisfaction of achieving the things you want and having a significant other that loves you because of who you are and not how you look, will be worth it.
Ok, I wrote too much. Anyway, I hope it helps at least a little. I understand how you feel.
