You are trying to claim that you are making a simple factual statement when in fact the subtext - which is probably obvious to all - is that in your opinion you don’t think people’s claims of impairment or dysfunction are valid unless they have a specific medical diagnosis that YOU feel is valid. And the proof of this is that your statement can be as true reversed. IOW, you have NO idea if they’ve been medically diagnosed or if any diagnosis or absence thereof is valid or not. It really negates your point.

And why does this all matter to me, personally? Because my own personal experience with the medical establishment is that they pretty much throw shit out there that may be valid or may not and relies heavily on both the doctor’s and the patient’s own subjective assessment. A sibling was for decades diagnosed as intellectually disabled when in fact he has ASD because they were unable to communicate effectively. I was diagnosed with a common mental disorder by one doctor and told there was no way I could have that by another. It goes on… And so I tend to be pretty sympathetic when someone says “I feel impaired by <condition X>” and I don’t feel a need to question whether or not they have <condition X> or if there was a formal diagnosis or not. Again, because many of those diagnoses are about as valid one way or the other has throwing darts. Could be good, could have missed something completely, could have misinterpreted what the patient said because they weren’t able to communicate it in that moment.

What is important is what the person says about themselves. If they want to say they have ADHD or ASD or whatever, it’s not my place to gate keep or question that. Nor yours.

Edit: To put it another way… your statement is about as useful as, when someone says “I just love this blue dress I’m wearing” pointing out that “well akshually that’s turquoise”. The point is THEY like the color.
