Michelle Knight, one of the three survivors of Ariel Castro's House of Horrors, thanked officers in a handwritten letter Cleveland police posted on Facebook Wednesday, and we've got all the details for you right here on Breaking Celebrity News.

"I am overwhelmed by the amount of thoughts, love & prayers expressed by complete strangers," Knight wrote. "It is comforting. Life is tough, but I'm tougher!"

In the wake of kidnapper Castro's plea deal last week, prosectors Wednesday revealed that Knight and the other two victims, Amanda Berry and Gina DeJesus, kept diaries of their torturous time in captivity at Castro's hands.

Cuyahoga County Prosecutor Timothy McGinty said in a sentencing memo that the writings confirm Castro "serially abused" the women "physically, emotionally, and sexually on a daily basis," comparing the women to prisoners of war.

"The entries speak of forced sexual conduct, of being locked in a dark room, of anticipating the next session of abuse, of the dreams of someday escaping and being reunited with family, of being chained to a wall … of missing the lives they once enjoyed, of emotional abuse, of his threats to kill, of being treated like an animal, of continuous abuse, and of desiring freedom."
