I'm so sorry about your son and the heartbreak you've endured. My friend's son has been addicted for years, in and out of jail, stealing from family members, losing any contact with his child, and making his family fear for their lives by threatening to kill them all. They believe he just might do it, too. It's a horrible situation to be so addicted that your brain is fried and the family that has loved and supported you lives in fear of being murdered. And it was nothing they did in his upbringing. They supported him, loved him beyond measure, and their other son turned out to be the epitome of what anyone would want their children to be. Some people seem just bent on destruction, and there is no turning them away.
