I wish I could give you a Like for this, because I agree with you. When I was in my early 20's I always had issues with reading. I knew something was wrong but people would try and convince me otherwise. People would say it's stress, word blindness, and so on. I knew I had dyslexia but I couldn't officially say it. At 25 I went for an assessment and was officially diagnosed with it. I've never been diagnosed with ADHD but I'm quite confident I have it. In fact, when I went to my assessment, the assessor said that my issues were 'almost attentional' as she put it. She gave me a quick ADHD test, to which I scored 47/50. She strongly advised I see a doctor, though me being me, I just keep putting it off because it never feels important. I think there comes a point where, when you know, you just know. It's an inexplainable feeling, but when you truly know there's some kind of issue that goes against social norms, you just know.
