LMAO up there with "i have bipolar, ocd, schizophrenia, ptsd, anxiety, borderlind personality disorder, depression. BUT IM NOT DIAGNOSED!"
I've really struggled with the apparent popularity of "self diagnosis" as someone with multiple properly diagnosed medical issues. I fought for years - the better part of a decade - to have my symptoms accurately diagnosed and treated. It was an extremely complicated, time consuming, draining (emotionally, mentally, and physically) process - and one that I couldn't have gone through alone. My parents had their (significant) issues that often did more harm than good, but ultimately I survived til my 20s because of them. My doctor's were all on my side every step of the way even when we wandered drastically of course (unknowingly at the time).
I endured a *lot* to get to a point of being diagnosed and appropriately treated. And I was still lucky - at that time the average time between "full onset" of Narcolepsy and diagnosis was 10 years, and I got mine in 7. I'd had "red flag" symptoms since I was a child and we'd began actively seeking help for them since I was 13 years old. Unfortunately teens are a terrible age to get things like this diagnosed since puberty can mask a lot of problems.
I used to be *quite* scathing of any hint that someone was claiming a diagnosis that hadn't actually been made. Depending on the circumstances I can still find my blood boiling. But my sister (10 years younger than me and much more "into" certain internet things than I) explained to me that it's often not as simple as Person A just woke up and decided they had x, y, z medical conditions or disorders. Lots of people live in places with little-to-no access to medical services especially specialist ones - and if they do, they frequently can't afford them. Even in Australia which has broadly good publicly funded health services, access is still dependant on getting referred properly, services accepting new patients, and of course on geographical concerns - the further you live from a big city, the harder attending appointments will be (once you even get one). Added to all that, most specialists charge more than the medicare fee so even if they bulkbill (meaning you don't pay + get refunded) you still pay the extra amount - I've never paid more than $100 out of pocket but that can still be the difference between eating or starving for many people.
Depending on the symptoms, people awaiting diagnosis may be unable to travel + attend apppointments alone, which means they need at least one reliable person they can ask for help to attend medical appointments. Of course having a "bad day" can mean after all that effort to get an appointment you still might not be able to attend and will need to reschedule (often a complicated process) and try again. Then, once you're actually in the room with the person who can diagnose you, you need to have your wits about you in order to provide all relevant information. The problem with being affected by a serious and untreated medical condition is that it takes an astonishing toll on your ability to function. Sometimes the Doctor can join the dots and figure things out even if you're not able to be an ideal patient. I was supremely lucky to have a doctor brilliant at diagnostics, he was the first to ever mention narcolepsy and without him who knows when I'd have been diagnosed.. But before I saw him I'd seen at least 2 dozen Doctors who all had enough information that - had they put the dots together correctly - they could have diagnosed me.
Anyway. As hard as I had it, I've learned that plenty of people have it far worse than me on the road to diagnosis. I was young and stubborn (meaning I refused to settle for being placated and had the time and ability to persist), lived in the suburbs of a capital city with my mum willing to drive me anywhere that could help me, we could always find the money for appointments and tests and treatments, my doctor's always believed me even if they drew different conclusions than I wanted (not EVERY teenage girl with seperated parents coming in has ONLY "family issues" to deal with, no matter how bad those issues may incidentally be).
I personally know about a dozen people who lack one or more of those things and are still battling to get an accurate diagnosis. And it is a battle. So I've learned to be a little more tolerant and forgiving of those that resort to self-diagnosis.
Those that make things up for fun and drama though.. ya, they still make my blood boil.
