Rose, I think the way he treats you is awful and I'm glad you're able to speak up and say how you feel. It really doesn't take much for a person just to say, "Thank you for all you do," and/or give you a little hug. That really doesn't take all that much effort and it makes so much difference.
It's too bad there's no one attending to your needs with the meticulous devotion that you attend to his.
I hope you are continuing looking into giving yourself at least some time off from this demanding patient.
