I keep seeing people say "I have X but I haven't gotten diagnosed yet". Pet peeve: you _think_ you have ADHD but you can't state that you have ADHD without a diagnosis. If you have a piece of bone sticking out of your leg, it's fair to self-diagnose with a broken leg. Mental conditions are much harder to lock down definitively, especially because ADHD, autism, and bipolar all share similar symptoms. My own personal anecdata is that the people I've known who suspected they had ADHD more often than not did but they (myself included) still needed a diagnosis before stating it as a matter of fact
