Sleep deprived Rant

I have a test tomorrow and its already almost midnight. I have been struggiling with my sleep schdule for a bit now, it just sucks because even if i fix it again all it takes is a couple of days when i have to stay up late to finish school work and suddenly i find myself not being able to go to bed.

I have no idea what im doing writting this i should either go to sleep or study but im too tired but not tired enough -_-
