I feel this era is already here. It's a fight between people who are weird, weirder, and weirdest, trying to prove who has the most problems and why they believe they have this and that medical condition, and that people need to try harder to "understand" them.

Maybe I have ADHD? Maybe I have autism? I've never been diagnosed, and with the state of the medical system in the US I don't think I WANT to get diagnosed due to the quality of doctors I've been seeing my whole life for chronic pain, and from the stories I hear from people who actually are on a "self discovery" journey.

If someone has ADHD, that's fine. Maybe ask your personal doctor for a letter or something to show your employers. But going around telling everyone you have ADHD and making memes about "ADHD" and saying stuff like "haha this is such an ADHD thing" is not helping anyone's case. The "normal" people (if they exist), will take you more seriously if you are more serious about a serious condition.
