I honestly didn't mean to come across as dismissive. Taking the OPs words exactly as they were written, I only meant to say that generally speaking, those responses are all quite expected, independent of any diagnosis. Having ADHD could of course make each of those bullet points much worse! But as the post was written, it seemed like textbook dissatisfaction that all of us experience when placed in a role that isn't quite right, and when that happens it's often easier to check out or become distracted. I don't see how ADHD stratagems could alleviate this without increasing unhappiness lower down. In the end, if you're not doing whats right for you then figuring out how to focus better is the real distraction.
I hope my response helps you understand why those things which seem universal aren’t necessarily universal for us. A lot of times we’re just disappointed with ourselves because we’re not experiencing the thing the way “everyone” does, and can’t find a way to that feeling everyone else expects.
