Sorry for your pain. I have known parents of kids who seemed to take a wrong turn in life and never could get them back. It’s hard not to blame yourself but the best any parent can do is raise them the right way and then turn them loose.
We raised him right but he took that wrong turn right off the bat and we literally never did get him back.
We are more relieved than grieving.
Relieved that he is no longer suffering in pain trying to live with his addictions.
A sad loss of life.
