(waves) cis person with non-gender dysphoria here! This is a bit unrelated to the main point at hand, but I'm going to throw myself and my experiences out there as a cis person with dysphoria, both body and mental illness related. Depression, dissociation, personality disorder problems, anxiety... And then of course there's the fact that I used to have an eating disorder and was kinda-sorta-not-really body dysmorphic. I don't feel that any of this is necessarily related to societal pressures so much as it is my own issues, but I know a lot of people with dysphoria who do have it due to society's expectations.
But the most weird example of dysphoria I have is species dysphoria (don't laugh). My brain sees my "correct body" as being a cat, gets very (irrationally) upset about being human-shaped and not covered in fur (fun fact: I, a cis girl, have considered going on T for the sake of increased body hair!), not able to walk naturally on four legs, etc., to the point of self-harm and depression. V describes it well in xer post here (xe, unlike me, is trans, and has both gender dysphoria and species dysphoria). And knowing that there is nothing I can do that will change my body enough to make it mine... It's soul-crushing. I would do anything for that. But it's impossible, so I just have to kind of learn to live with my dysphoria the best I can. Which sucks, but hey, grant me the serenity to accept the things I cannot change and all that jazz.
So, yeah. Dysphoric but cis: it's a thing.
To refer to the original point (I'm cis so feel free to ignore my advice here, heh, but I did my best):
What's helped me and some of my friends the most is this: when you're confused, focus on what you want (for example, someone might want to bind and go on T but be referred to with she/her pronouns; or maybe they'll want to use they/them and get bottom surgery without going on hormones or getting top surgery; or any other combination. transition isn't all-or-nothing) whether than What You/Your Experiences Truly Are Deep Down (the people mentioned above might identify as gender-non-conforming cis women, non-binary people, trans men, none of the above... whatever feels right to them). Live the life that will make you most happy; labels describe what you want to do, they don't decide it for you. If you're dysphoric and confused, figure out how you want to deal with that (therapy, body positivity, changing your location/friends, makeup, surgery, medication, hormones, exercise, etc etc, whatever you think will help you) first; if you're unsure what the right labels for you are, that's okay, you have your whole life to question them, but wouldn't it be nice to do that in a body that feels like it's yours?
