Plz help? question about god?

ok im 15 and i have been very confused lately. ive been wonderng what is life about? is god real? do we really go to heaven when we die? what if there is no god and nothng but a big endless black space where u are all alone and cold for eternity? i suddenly dont see any reason for life anymore. i am extremely far from killing myslf by the way coz i am very afraid of dying now. what about the words of kerry packer after he died for 8 mins and came back "the good news is there is no devil, the baad news is there is no god, there is nothing" im really upset about this and scared. what if u just dream 4eva and really want to wake up but u cant coz ur dead? i have very upsetting thoughts on death. does this make me depressed? i dont know. plz can u answer me? and plz no answers that say "there is no god" or anything like that plz im very upset already.
