Rarely prone to hissy-fits
I'll disagree, actually. What someone's internal model is and how well it works for actually describing the reality they're trying to work with, well, that's their business. I dunno about you, but I don't really care if it's valid or not, or even what it actually is. In a sense, it being valid or not isn't even the right question. If it works for them, good for them.
But that's kinda the keyword: it's THEIR business, not mine.
It only becomes my problem when it turns into demands that everyone else must meet, in order for them to pretend that reality fits their model.
I'll add a couple of personal anecdotes to illustrate this
On the one hand... I persistently and consistently think that I'm about 4 inches taller than I am in reality. I frequently find myself surprised that I can't reach a shelf, because my brain is quite convinced that I should be able to. It's been that way since I reached adulthood, and it will not go away.
In a sense, this would be a bit of body dysmorphia, which is conceptually similar to gender dysphoria, but with a very different focus. But... I am well aware that my brain is a liar. My brain is wrong. My brain, and it's stupid ideas about my existence in this world, don't matter to reality. No matter how hard my brain wails and carries on, I'm not 4 inches taller than I actually am. And I'm okay with that. Thus, it doesn't rise to the level of being a disorder.
On the other hand... my best friend has always viewed herself as a redhead, and thinks of herself as a redhead. She dyes her hair to somewhere between a strawberry blonde and a light copper. In reality, however, her hair is blonde, and quite light at that. But if you mention her being blonde, or refer to her as blonde... she absolutely loses her ****. She actually breaks down and cries, and gets angry about it.
I'd say she also has a bit of body (or hair) dysmorphia. And because of the level of emotional impact it has on her, I'd even arm-chair-psychology that as being a disorder. Luckily, it's one easily treated as hair dye is ubiquitous and easy to do in your own home.
On the gripping hand... at the end of the day, no matter what our internal views of ourselves have to say about it... I'm short and my best friend is blonde.
