I am exhausted with life?

i'm tired of everything, repeating the same nothing every day. i'm not sad, but i'm not happy at all. i just don't feel anything anymore. it's like eternal boredom. and i'm both mentally and physically exhausted. i have no purpose and feel like my prison sentence was being born. i don't know where my happiness went, it seemed like it was just here and now its gone. don't tell me to seek help. seeing a therapist will only make me angry because i won't tolerate others telling me i have problems. i don't know if its school or what. school seems to suck my soul dry, just repeating the same horribly monotonous routine. and the past few months i've been confined to my room alot. i had so many friends before and now they're dwindling. everything has gone straight down the drain. i want to burst out of my skin like a freaking insect. what the hell is wrong with me??!
