After the death of the person that was the closest to you,you changed drastically without even noticing.

that made you argue with everyone even over stupid things,but you used to argue with Carl more.

You didn't even do it on purpose, but you were so hurt that you didn't even know why you acted this way,you even started hating yourself, you couldn't stand yourself either at this point.

in the middle of an argument with Carl,he snaps.

"what have you become?''
