Right now the most difficult thing for me is being aware every waking hour of where Doug is and what he is doing, without him actually knowing I am watchful. He wants to function as independently as possible but he does have cognitive impairment and often leaves water running, food containers open on the counter, the fridge standing open, and regularly goes through the house without his walker. Our house is very old, has uneven floors and several single steps between rooms. He has, of course, fallen many times, often requiring trips to the ER. By the end of the day I am exhausted as much mentally as physically.
