I know the feeling.
But how's this for a comparison:
Suppose you had stage III cancer, or some other disease or some disability that was impacting every area of your daily life, such that you were constantly seeing different doctors and playing around with ways to manage with your disease/disability.
Wouldn't that be occupying your mind to the point that you would rarely be thinking of anything else? "Donald Trump? Ted Cruz? I may not live long enough to vote against either one!" Etc.
Transition is a huge change. Dealing with being trans, whether you transition or not, is a huge change. Whether or not you believe gender is a social construct, it permeates pretty much everything about your life, at least every interaction with another person. It's not like it's something you can relegate to a half-hour or so a day.
FWIW, one of the (these days few) advantages of my work (computer programmer) is that I can forget about gender while I'm focussed on a problem. But then I talk to a co-worker, or go to the men's room (feh!), and it hits me in the face again.
