Overview
It's not your responsibility to fix the problems in one of your friend's lives. You need to be supportive of them, but you have to stop putting so much pressure on yourself. And if they choose to ignore your solid advice, you can't be frustrated by their continued failure. Sure, you know that they are making a huge mistake, but they don't -- the only way they will learn is through trial and error. Take a more hands-off approach to your friendship. It's the best thing for both of you.
