My friend recently returned from rehab due to a horrible addiction to Xanax about two months ago. He came back enlightened, focused, and determined to fix his life. He became closer to God, and those friends who were great influences. But now I have come to realize that within the past few weeks that he is slowly taking bars again, and I don't know what else I can do that rehab didn't already do. I've always supported him, loved him, and I want the best for him. He loves the advice that his family and I try to give him and I know he wants to do better, but he just never puts those words to action. I'm all out of ideas, I've never felt to useless.
