I cannot express the depth to which this poem disturbs me. More than most I understand the gratitude we carry for those whose torments made us stronger.
"Thank you for those bruises and those scars"

However, you are giving thanks for being in the worst of the situation still.
"Most of all, I thank you for the emotional and mental trauma that haunts me till this very day "

I'm sorry that you had to deal with the abuse and emotional isolation. I hope you are able to exorcise these demons through your writing.
