Considering ADHD Diagnosis as an Adult

Hey all, I've never been diagnosed with ADHD, and for most of my life, it had never crossed my mind to even look into it as an adult. Recently, my parents told me that they both exhibit many of the signs for ADHD but that neither of them ever looked into testing for a diagnosis, either. Since I started looking into it, I noticed that my everyday normal characteristics might not be normal for most people. I hyperfocus on things I am interested in to the point of extreme exhaustion, easily and constantly lose focus on everything else, am incredibly spontaneous, quickly drain my mental energy, experience severe depression and anxiety, and other maybe-signs on top of that, too. Growing up, I had the misconception that the only type of ADHD out there is the one often portrayed in media—talking and thinking non-stop, fidgeting all the time, and the like. I was wrong, and now I'm wondering if much of my currently unexplainable pain and conditions could be linked to ADHD. Not that my life would really change much if I get diagnosed vs not, but... it'd be nice to know, you know? Do you have any post-childhood encounters with conditions you never thought you had? Did that bring some clarity into your life? Should I try to get tested?
