I sympathize, I feel like my executive functioning problems are always blamed on my depression, even when my depression is in remission thanks to the meds.

When's the last time you brought it up to the doctor? (If it's been awhile, maybe let them know that it's still a problem.) Have you tried making an appointment about just this problem? (It's more convenient to bring it up at the same time you're going in for another reason, but I've found that makes it more likely for doctors to brush off some things.) Can you go to a different doctor? Maybe your GP instead of your psychiatrist?
