Turning Lemons into Lemonade... Eventually

Sorry for the cliche, but it's 7am here, and this is the best I can do. My mother-in-law lives with us and was recently diagnosed with Alzheimer's. Every day there's some new twist to her behavior and demeanor, all designed to drive me batty. Yeah, it's all about me. I'm planning to use the experience in an upcoming novel, and I have the major plot points in my head, but I've been unable to actually write it, in spite of several attempts. It's too fresh, too close, and I can't find the humor in it yet. The best I can do is keep a journal, so that I don't forget the details. I can tell you this--my take on Alzheimers won't be "We Love Dear Grandma--She's Just Having Problems." Most days I have to remind myself that I wouldn't do well in prison...
