IMHO
I don't know that suffering has no redeeming value. For those of us with strength to overcome it I think the siffering helps us to find that strength. A few years ago I wrote a poem that I still believe is what suffering did for me. Of course I have no idea who I would be if I had grown up in a family where there was no abuse.
I Am
I am my father's daughter
And I am my own creation.
Through the pain he inflicted
I found strength to endure.
Through the anger and fear
I found courage to confront.
Through indifference and neglect
I found inner strength and self-reliance.
Through his constant criticism
I found the desire to learn and rise above.
Through threats of death and hate
I found the ability to survive and thrive.
I am my father's daughter
And I am my own creation.
It took me years to realize the lessons learned. I spent many years in therapy learning that as a child I had developed many skills to survive the years of abuse. But I did learn and those strengths are still there
