Cover art for Roots lyrics by In This Moment

I believe this song is about how Maria's father sexually abused her as a child then abandoned her and her mom. He's her roots but she's thankful that his actions has made her stronger and he finally left.

"I thank you for the hole you dug in me Filled it with cement, sunk me in your sea" He scarred her.

"Thank you for being so obscene" The sexual abuse

"I thank you for never facing me Swimming in the mud, never coming clean I thank you for nothing in between" I don't think he ever fessed up to what he had done to her

"Yes, I thank you for leaving" She glad he left after the turmoil he caused her

My Interpretation
