Earlier quoted context omitted.
There's a very helpful method for being confident that you did something right, and while it may not be enough for people with compulsive disorders, it's great for many situations: https://en.wikipedia.org/wiki/Pointing_and_calling I think it works by recruiting more of your body & brain to the task of attending to something. Maybe the anxious could video themselves doing it, and watch it back later.
I don't suffer with this too much, but while the "point and call" method works well for one-off activities it doesn't do much for regular ones. I end up asking myself "I remember pointing and calling... but was that today or yesterday?" Is there a way of using point and call, or a similar method, for helping with that?
Point at pill bottle. Taking my pill on Saturday.
Or something like that?
