Ann, how sad you must feel, how terribly sad your nephew must feel. I do, and it's no one I know. Gratitude for those whose life paths crossed ours and made all the difference. A young lieutenant took my new-recruit 20-somethng hard-drinking brother under his wing for the first few years as a spiritual mentor, it made all the difference in my brother's newly-awkened spiritual life. For a lot of years before the lieutenant, there were very real doubts whether brother would survive his 20s physically due to the drinking.
25+ years sober years later, my brother is alive well and thriving, with a loving half-grown family. Wherever that lieutenant is, I hope his life is the same.
