Being kicked in the teeth.
I care for an 89 year old mother with Alzheimer's. She's not at the point yet where she craps in her pants and can't even feed herself, but it's still a daily, depressing grind for me. Today, for whatever reason, she was semi-lucid. I made her laugh. Things were almost normal. She remembered stuff from long ago and we had a good day. For me, it felt like I could catch my breath for a few hours. An oasis of relief in a desert of pain. And then for no reason I could understand....she suddenly went back into her Zombie mode and I felt viciously kicked in the teeth...again. Alzheimer's must have been created by Satan. You look so hard for a glimmer of hope, of the parent you once knew, and you see some signs and become hopeful, and then this disease slams your head into the pavement (again)..
