Do ur charectars do this to u???its that bad?

im 13 and in a dream i got inspired to write all the aspects of life into one larger than usual family.Thats fine, except that they are CONSTANTLY in my head, im doing pages of notes,planning,writing,discovering,liste… and they just dont have enough to say!! i got a cast of 20 charectars and they keep asking for more events, more words i cant not think about them. and i havent even finished the intro. now im terrified of dying that they will just disappear and their unique and ageless stories to die. from gangs, to 19 year olds with wasted lives in the streets, to interracial love affairs!! to 10 year old philosephers!! to racism, to beauty and consequence- to uality even------im 13 and ive seen too much in this world and i felt too much now these feelings have got faces, and voices and im scared i wont be able to conserve them to let them out...... any adivce? its really that bad!!
