i kept dozing off and waking up the entire night. and everytime i woke, there was just one question in my mind. why did things change overnight? was it me? what did i do?

those dreams i keep having only makes it harder for me to let go. its like im self tormenting. my mind is working 24/7, but not on my exams. im so certain i'd screw this up, no matter how much i hate it, i know i will. sighs. im just that useless.
