As I read other people's comments, my diagnosis experience seems somewhat unique. I may be misremembering the exact sequence of events, but I'll try my best.
As a young kid, I did okay in school. My report cards often noted that I did really well on the tests, but I often forgot to do my homework, and since homework was a large portion of the grade, I had lots of Bs and Cs. On the standardized testing we did each year, I'd score well above my grade level on everything except the listening portion, which was just average. In junior year of high school, I made it a point to have no missing assignments. Even if I didn't finish my homework, I'd still turn something in, and suddenly I had straight As.
Around the time I was 18, I began trying a variety of antidepressants, mostly SSRIs.
I was probably 20 years old when my parents suggested that I see "Dr. Feel Good". In their experience, he handed out prescriptions like candy, so he'd probably give me whatever I asked for. When I went to him and explained my struggles and how I felt they were indicative of ADHD, he told me that I couldn't possibly have ADHD since people with ADHD don't get depressed. I think he did end up giving me a 30 day prescription though, and suggested I find a more specialized doctor.
I think it was after that that I began seeing a psychiatrist. The psychiatrist again put me on an SSRI, I think Zoloft. I took it for a while, but eventually got fed up and just stopped taking it. I think it was when I told him that I stopped taking it that he finally gave me a prescription for Adderall. Or maybe my time with him overlapped with the next paragraph.
Somewhere around that same time, I had dropped out of university and decided to take classes at the local community college while I figured things out. Somehow, I learned that the community college offered learning disability testing, so I signed up. From what I remembered, I did really well on everything except (surprise, surprise) the listening portion. I was told that my results indicated that I have an "auditory processing deficit". I eventually wound up taking the test results to a new psychiatrist, and they put me on Adderall right away.
Honestly, I'm still not totally sure if I'm "officially" diagnosed as ADHD, but I've moved around a bit and changed doctors a few times, and 15ish years later, I'm still getting ADHD meds.
All this is to say that there's lots of doctors out there that won't take you seriously, and/or have outdated understanding of mental health, so whether or not you have ADHD or anything else, don't give up until you find a solution that works for you.
He's pooped in that stance since he was a tiny kitten. We have litter boxes of various styles and sizes, and I've even tried setting up an identical box for him, minus the lid, but he seemed to prefer the one with the lid. ๐คท
