How do I do this?

How do I do this? I'm not doing it very well. I don't want to talk to him because when I do it is a work, a lot of work to try to relate to what he is remembering or not remembering and what I do or don't know that will help us both. I am so sad, sorry and burdened. I feel guilty and want to run away, I love him, I want to help; but am helpless, angry, frustrated, bitchy. I pray and ask God for direction. I overeat and try to find energy to cope. I exercise and feel better. Then another day, another cog slips and around we go again. Gropping through the mist. Dear God, please help me do your will.
