I have been there, it is called my father’s drug addiction to prescription pain pills and it started when I was small. He was in a bad car accident and he recovered by learning how to live off pain pills. Pain is both physical and psychological and I believe that the physical suffering can partialy helped by psychological means.
Now his addiction got out of control when he tried to commit suicide with my mother, the family dog, and I in the house by running his car with garage door shut. I know this is mental anguish but he put everyone in danger. This was a lesson in forgiveness and understanding of sickness. He was mentally sick.
He lost his battle with his addiction to the pain pills. This is where I had to learn the hard way to accept death. Life and death is a cycle that so many do not want to accept because we live in a world that wants to be young forever and never die. This was a storm that I had to hang on because this was bumpy water.
