Forgiveness initiates the healing process
Especially and importantly for the forgiver
Even though forgiveness might not take the pain away immediately,
Remaining in that state of forgiveness would speed up the healing faster than any drug/medicine

Free the punisher, forgive the abuser
Don't lay the blame on yourself either
The pains/regrets would try to resurface
They could even bring tears to your face
But strive to not walk out of forgiveness
Even if you can, say a word of prayer for you and the person(s) in question
That's how you hold on to your peace & freedom.
