my world as i know it is ending

i dont knw what to say anymore. i think i have just lost it.i feel like running away so far noone will ever find me. im hating every moment of my life now.i feel like noone understands me. i wish things would get better,but how?by praying? is God really there to help us when we need him? im starting to think what i believe in doesnt even exist. cause if it did,why does bad thing keep happening? i just wanted to pass so badly i lost my dreams of wanting anything else. i feel so dead.so useless.so teary.i dnt knw what im gonna do with my life. and im just sitting waiting for the day i tell my parents everything and then that moment id rather be dead!
