Open Question: why should i continue? i am losing the will to live.?

i have been planning this day for a while. the day of my death. tommarow is the day i have to chose if i am ready to go. at first i was sure i wanted to go but last class period has me now unsure. i didnt plan on telling anyone because it would cause too much chaos but i did today. a friend of mine told me he cared & i felt like the biggest jerk alive. i dont want to hurt anyone but the longer im here the more i lose the will to live. two people who want to help me but i feel too lost to turn back. is it reall worth it?
