he had a difficult child daughter years ago. at age 35, she overdosed on oxycontin in spite of the parents best efforts, in spite of their money, in spite of them both being loving good intelligent parents who had lost their only other child at his birth. the couple then joined support groups and spent the better part of the next years counseling other families, wiping tears, organizing POTADA and AA groups and toughlove grps. he said the only way to survive a difficult child is to detach and let them choose their life and back off once they are over 18. do not enable or cover for the difficult child, no money given, no guilt. he said we must live our own lives, he believes it is out of our control. he is an amazing man in his 70's. his wife never got over it and works to keep her mind occupied. they lost both kids.
