That cisgender doesn't really exist? I mean, how can I tell, maybe everyone else I saw on the street today was uncomfortable with their birth sex and stuff expected of it at some point, but learned to deal with it, or hide it, maybe even like some aspect of it, just like I used to do, and that's a normal thing to do, that I'm just worse at it than everyone else, or temporarily weakened by all the other trouble going on in my life?
