I would do the same as the previous poster mentioned. Mention you have a family history of ADD and would like to explore the possibility that that's a contributing problem. I would avoid discounting the depression entirely, that kind of undermines their clinical skills, but present it rather as a "maybe this is a contributing factor". There are lots of meds to treat ADHD that are effective and aren't stimulants so you wouldn't even necessarily need a controlled substance. I would hope your doc wouldn't necessarily jump to the conclusion that you're drug seeking just because you're trying to better understand what's going on in your body.
Good luck.
