Right now he is on Creon, so he is able to digest food and get nutients. We are very active and so the lack of energy and strength to do what he used to is frustrating and depressing him. He also has some pain from his kidney being blocked and getting irritated.
For me it is working through the situation with him. One minute I'm the greatest thing in his life, the next he's angry because what ever is bothering him at the moment and I become the target.
