Drugfree.org has a great post from a parent who’s been through the wringer and is speaking from the other side.
When speaking with a struggling parent, she asked him what he wishes he would have done differently. He responds
I would have learned to listen.
First, I would have learned to listen to my son. …
I would have also learned to listen to counselors and parents. …
I would have learned to listen to my own internal struggles about what I am told….
Finally, I would have learned to listen to my heart and my head.
Please go to his post and read his discussion of each of these. It’s a great post.
