As much as we would love to be able to wave a wand and make our friends' troubles disappear, we can't do it- we can only be there for them, offer the best advice we can, and wait for them to make their own decisions. It's hard, I know- believe me, Anon, I know how hard it is to watch someone making a bad decision while claiming it's a good one, despite all available evidence to the contrary- but people can only learn things by doing. The best you can do is offer tools and hope they decide to use one. It's not your life; it's not your battle. Hang in there.
