“Here, hold this,” they said and gave me a stone.
But I couldn’t hold the stone while I swam in the sea so I chained it to my ankle.
The weight kept pulling me under and I couldn’t keep my head above water.
“Please, take the stone back,” I begged them.
“That is no longer ours. It belongs only to you,” they said and swam away.
I was alone in the sea with a stone chained to my leg. It pulled me down, down, down and I knew I would drown if I could not become free. The stone was not mine but the chain was my making. Only I could unfasten it. My survival was completely up to me.

Nice story. I assume forgiveness is unfastening the chain and letting the stone drop to the bottom of the sea.
Well Done!
Yes, there comes a point we only hurt ourselves more by not letting something go. We keep the wound infected so it can’t heal.
