I think the coming trend is chronic illness. I have to be careful here, because if you're critical of spoonie culture or online sickfluencers, that's like saying Beetlejuice three times, and the chronic illness community can be extremely energetic when they feel they need to correct someone.
So, to get my disclaimers out of the way: yes, I know invisible disabilities exist; yes, I know chronic illnesses often have comorbities (know that from personal experience); yes, I think it's likely that chronic illnesses in women and girls have not been taken as seriously as they should.
But.
There's a definite trend in online spoonie/sickfluencer culture of encouraging girls - and it really is girls and young women - to embrace their illness as an identity, with a lot of shaming of those who want to get better. Parental affirmation isn't as obvious or extreme as with gender identity, but it's there.
And there's definitely an overlap in a certain type of extremely online girl:
- Possibly ASD/ADHD, maybe with a diagnosis, but those without a diagnosis aren't very shy about self-diagnosing and identifying as vaguely "neurodivergent"
- Very likely a baroque sexual/gender idenity, it may be "demisexual enby" or similar
- A whole laundry list of chronic illnesses, allergies and intolerances, often with vague diagonistic criteria, often explicitly self-diagnosed ("I think I may have condition x"), sometimes speculating on whether they might have DSDs
- Probably a history of EDs or self-harming
You can find discussions in certain trans/queer subreddits where older members of the community are scratching their heads and saying "what's with all the young queer AFABs using walking sticks these days?"
I don't know what we do about the Tumblr girls, except I hope they have someone who can be an adult. The parallel with EDs is very obvious, except no parents were affirming that.
