The Horrible Agender Feeling of knowing you will Always Be Perceived as A Gender, regardless of what it is, even by other queer people because we live in a gendered society.
The Horrible Agender Feeling of knowing that transitioning won't do anything because you'll just go from being perceived as one thing you absolutely aren't to another thing you absolutely aren't.
The Horrible Agender and Nonbinary Feeling of having dysphoria symptoms not taken seriously because you don't want to "fully" medically transition to the opposite sex, so it doesn't matter if having a uterus or any other one thing makes you want to kill yourself, unless you're willing to start hormones you don't want to take and get a bunch of other surgeries you don't want to get, go fuck yourself.
The Horrible AFAB Agender/Enby/Transmasc Experience of wondering if your identity is a reaction against misogyny, or if it's actually a part of who you are (spoiler alert: it's a real and valid part of who you are, but the misogyny really doesn't help).
The Horrible Agender Experience of other queer people not understanding or caring about your identity. "Oh, so you're non-binary?" (No, that would imply I have a gender identity that is not male or female. I do not have one at all.) "Oh, well you allow yourself to be perceived as a cis woman, so you must identify as a woman and that must be a real part of your identity" (I allow myself to be perceived as a cis woman because I don't have a fucking choice because transitioning would be just as bad. Shut the fuck up and get hit with a thousand hammers)
The Horrible Agender Experience of being locked in a box that will never fit and never open, and you can change the shape all you like, but you'll still always be in a box
