Lee-- Props to you for being such a good son. Caregivers need care too and it's not a good idea to neglect your own needs and life. Maybe you can separate what *needs* to be done from what can wait. Medical care and living accommodations are urgent needs, but sorting photos? It can wait. As long as the photos are protected from the elements--why add to your responsibilities? Build personal time into your schedule to do things you enjoy and as Keith mentioned--no need to force anything with photography--it will be there when you want it. Take care.
