Just to add: education and diagnosis is getting better, but there are still a lot of psychologists and psychiatrists who have little to no education on adult ADHD. They can use the diagnostic criteria meant for children and often get it wrong. You may find a provider who has updated their education, but the best chance of an accurate diagnosis is to look for somebody that specializes in diagnosing adult ADHD specifically. If the diagnosis involves a detailed history and several appointments with multiple tests, that’s a good sign. If it’s just regular 30-60 minute meetings where you talk and they say you don’t have it, get a second opinion from someone who specializes in this.
I can’t remember the specific examples (surprising nobody), but I have had at least a couple occasions where I found traces of something I’d done that showed me I did actually react that exact same way some while previously and forgot about it entirely. In one case, a friend stopped mid conversation to say, “Wait. Haven’t we had this exact conversation before?,” and I while it wasn’t as concrete as finding my own evidence, I was pretty sure he was right.
It’s almost like a coping mechanism, even if I don’t do it intentionally. My life is a book, but at any given moment I might not know what happened on the last page or three. So I have to just figure it out and act how I would act even when I’m clueless.
