must.......stay.......awake

i really want to take a nap, but im scared if i go to sleep i wont wake up for night class. so im gonna try and deal with it. i've been walking around like a zombie all day. i cant quite focus on anything for longer than a minute. today in class i was reading something to myself and i had to reread each sentence at least 5 times because i would forget in mid-sentence that i was reading and i wouldnt pay attention. boy.
