Hazel, the first three words of your post says it all. "My adult son." We don't stop loving them once they become adults, but our responsibility for them has ended. He has to find his own way. Read the threads and you will see many, many mothers here who haven't heard from their own sons in weeks, months, and sometimes, years. We have to let them go because they are going to do whatever they are going to do and you cannot fix them. Many times, they do come back and honestly seek help. I pray that your son with choose the right path. ((((HUGS))))
