I do understand your fear and worry.
My son....alcholic/addict was missing for 14 years.
All I could do was accept the painful situation
I turned the outcome over to God.
I stayed sober..my AA friends were extremely valuable.
I always thought of him onn a warm sunny beach.
Healthy and happy. I doubted I would ever know.
Several months ago...he contacted us...and yes from a
beach town. He has now relocated and living with my daughter.
He has a job and they enjoy each others company.
Prayers coming your way..
