Love and support never hurt. I always just try to send my brothers messages of love. What they are struggling with is so huge, and any day they spend sober is a miracle. So over the years, even as the alcoholism has kept us farther and farther apart emotionally, I let them know, very simply, that I love them. They don't need or want my "help" in getting sober/recovered - I would be little or no help to them anyway!! All I can offer is to try to love and accept them just as they are today.
Peace-
B.
