Struggling with Severe Executive Dysfunction

First and foremost, repetition. I have this stupid checklist in my head. I go over before I leave the house for work. Check the back door is closed/ turn off the A.C. /make sure the fridge and the cabinets are closed./ Turn off the lights. Even if there's no rational reason for some of those things to not be right, I check them tying them together as absolute musts before I leave the house. Ive have certain things, I have mentally tied to my roommate. Like a game of "where you gonna be when Jesus comes back". I dont want him to see my dishes in the sink at all, or catch my bathroom light left on, or my food prep in left out. And I find myself like strangely running around cleaning things up anytime he is present. Of course if you behave this way, they're going to think you're weird, but that's way out the door anyway, and they'll likely appreciate that they can see you're trying.

I don't have any advice. But I just learned how terrible my executive dysfunction is and it makes me wonder how much that is tied to things in my life

Maybe try the app sweepy? I know part of my execution dysfunction is identifying what needs to be done, and the app helps alot. I find I'm basically "tricking" myself into doing shit; like if I do 5 minutes in the kitchen, maybe it won't be so hard to keep going. Baby steps, good luck!
