Im extremely pissed off and depressed?

ive been having a rough time at uni, i failed an ignment and i cant find time to repeat it because i have other major essays due and exams coming up. im sick of going to lectures and i hate everyone there because they treat me so badly for no reason. the lecturers/tutors scare the crap outa me and its like they want me to fail, i dunno. i just want the holidays to start so i can be out of there and with my friends and drinking and partying, how do i deal with this bulls*it ! i cant stand it
