I mean your sister is partly right, you won’t completely forget it’s there but especially nowadays we have lots of things that can help make life easier, and that’s true for a ton of difficulties people have regardless of diagnoses.

The general practice of minimalism makes things soooo much more manageable for me, it reduces the amount of things i have to think about and the amount of distractions around me. It doesn’t magically cure me of inattention, but it takes it from being fairly overhwelming to being merely frustrating.
