there is a very real tendency of teenagers with anxiety disorders self diagnosing with considerably more stigmatized and impairing mental illnesses (e.g. schizophrenia, DID, personality disorders), but the best response to that isn’t to get angry with them for “appropriating” lol. instead you show them coping resources for the problems they’re actually having and deemphasize diagnostic categories in general. if an 18 year old is claiming to have alzheimer’s, they’re probably making an innocent mistake and are in genuine distress. be kind.
Also I think this trend comes, at least in part, from how brushed aside anxiety disorders can be. If your parents and teachers dismiss you with ‘oh everyone feels anxious’, then inevitably you’re going to start thinking that there must be something else going on with you
”You must feel very scared right now; let’s talk about how to help you personally, tailored to your symptoms” will always be more helpful than “stop faking (X) for attention”. If theyre that desperate for attention or an explanation, something is wrong.
