It takes time, HH. And this is not an easy road we travel. There are turns and bends and sometimes you end up back at the beginning again! I, too, tried it all with mine. I finally reached a point last year when I stopped. Then he came around. Hopefully, yours will realize where he's headed before its too late. Meanwhile, attend meetings, come here for support, find a close friend to talk to who offers only a listening ear and not advice. Often when we open up and explore out thoughts, the answer is in the questions we ask. I pray you find peace in your journey. I pray your son finds recovery. I pray your daughter finds a way to love her brother but reject his choices.
