"Lost my morality" is something that occurs when you lose your last friend from your hometown. While everyone else has moved away, you are still at home, resulting in insanity, aka "lost my morality." Morality in some situations can sometimes be a reference to someone's mind and sanity.
"Thought I would inform you that in the short time Mallory has been gone I have completely lost my morality."
