Need your expert advice in commiting suicide.

I am so tired of all the lies and all the decite, people who call themselves my friends stab me in the back and don’t even care about other peoples feelings. I go to school faithfully to get an education and professors treat me like shit and like I am worth nothing, Do I have to pay for this crap? I have attempted suicide twice in the past, someone always found me passed out on the bathroom floor. I would like to make it happen for real this time, I want to kill everyone who has ever been mean to me especially the ones who claim to be my friend and shh…shh behind my back and after there all dead I take my own life and that will be the end of it, and everyone will be happy, “One less mouth to feed; how good does that sound?”
