So sorry for your loss. You are not alone. I have lost my father-in-law in 2008 to this beast. To add insult to injury, my only sister was also taken by it to in 2011 as well as a dear friend in 2012. I understand your pain. My friend had this beast for almost 10 years before it went into high gear. My father-in-law for two. My sister, for about a year. I pray every day that they can find something to halt in in its tracks, better yet a cure. My thoughts and prayers go out to you as you mourn the loss of your father. I took care of my sister and helped with my father-in-law. It isn't easy whether you care for they or whether distance separates you. Again, so sorry for your loss...
