I feel horrible

I just feel so horrible right now. I feel so fucking depressed, and thats making me lose a lot of sleep which causes me to be tired the next day. and with exams just around the corner, how the fuck am i suppose to study? i think i'm not gonna do well. this is a horrible time to feel this way. its like a fucking chain of horribleness. Depressed -> lose sleep -> tired and cant study -> feel more depressed -> lose more sleep. and the cycle just continues. fuck my life. i just really really wanna die. its not like as if that will affect anyone
