Few things in life are more frustrating than watching someone you love suffer. Particularly when they're making the bad decisions that lead to their suffering, and they won't take advice from anyone. You can't stop them, you can't help, you can only watch.
Sometimes you wish you didn't love them. Or at least not hear about their mistakes. But it's like watching a train wreck; you can't turn away. And you can't turn off your heart. So you get to suffer along with them.
I think the only reason people ever become parents is because they simply don't know any better. Or they do, but they think, it won't happen to me. My kid will be different.
And sometimes they're right. Their kids are different. Their kids avoid all these pitfalls and snares and make it to adulthood. I rejoice with them. But sometimes, the kids don't.
All I can say any parent going through this, may God keep and bless you. And pray that our loved ones make through with their fingers and toes intact with minimal scarring. The old saying goes that you can't find any atheists in foxholes when the bullets are flying overhead. I'm not sure if you can find any parents that are, either.
