you NEED cleaning ADD? No, I think you mean OCD. ADD = not focusing on anything, hence, not getting much of anything done.
also ADD does not = not focusing on anything. It usually means not focusing on lots of things, and hyperfocusing on some.
in need of some serious cleaning/packing/cleaning
and the process seems overwhelmingly large.
so lots of little tiny tasks she can do and check-off that go with the ADD brain would prolly be good, too.
