Hmm, deal with it? I don't think one can. I just accept it because I have to, but that's it. I'm 5,1 too, I think (American measurements, argh!) and I live in the land of giants (the Netherlands, average guy is at least 6' here. Women and men are almost always taller than I am) so yeah....It's all relative. It feels like a double stab from nature, making me trans and on top of that, way shorter than even the average female. I've been wondering if just moving away to a country that doesn't have giants would help.
In any case, just know life is not all about size. Sure it makes me dysphoric a lot of times because in my eyes, I'm a big, strong guy. But we can't all be big strong guys. Focus on your other assets and do not dwell on the things that you can not change. I try to keep telling myself that too, and most of the time, it helps to feel better.
