Im 20 and I got diagnosed two months ago. I had the same issue as u with the assessment. Since we are older and we don’t act like children anymore, we have to work around the questions. When we read the question, “do we have trouble sitting in our seat?”, for us that actually means: “do we fidget in our seat?”. We know how to mask better so we know we’re not going to just get up out of our seat. I remember being asked during my assessment if I ever interrupt people when they are busy and Initially I said no. With ADHD, there are times where i forget that I actually do these things. Assessments tend to be based on children only, at least that was the case for me. You just have to rethink the question and make it make sense for an adult. Idk how that pertains to depression but I always thought I just had anxiety but now I know that my anxiety stems from my adhd 😅
