If checking the calendar isn't incorporated into a daily routine, it's obviously not going to work. It's a shame your former boss was so disconnected from the experiences of those they're supposed to be helping.

If it weren't for my anxiety, I'd never remember anything. That, and putting things to remind myself in places that I know I'll look. Lately I've been putting my keys on a particular table, next to my medicines, so that I remember to take the medicines before leaving for work. (Note - I tend to forget my meds on weekends when I don't go anywhere, but it works 5 out of 7 days!) Sometimes the feeling of anxiety, the thought of, "Have I forgotten anything?" compulsively makes me check my pockets and look around. Apparently I've worried myself enough about forgetting lunch, that the "look around" routine has started to include a fridge check every morning.

Anxiety sucks, and sometimes it amplifies my ADHD, but other times it helps fight the battle against it. I almost fear treating my anxiety, out of worry that my executive dysfunction might get worse. Ahh, the neuro-spicy life.
