My heart goes out to you. Am thinking the Dallas area certainly has every kind of social services. If you, God forbid, were incapacitated suddenly, they'd need to be plugged in to local services. Maybe it's time to give yourself permission to make the contacts, turn them loose? You're going to be far away. Perfect, practical reason and timing. Might check with a couple of the larger churches also. I go to a senior Bible study group that has a few mentally slow folks in it.
