Growing Up, when you have to let go

so i've been sclackin on this lately but i have been running wild the last week. as school approaches and the grind starts up; how do you keep pace with yourself and your family? i'm of age now, outta high school and what not; so when is it going to be my time to live? i have two sisters, a nephew, and a dad all living under one disfunctional roof and i believe that's grounds for any college student to want to leave. so in a world of chaos, how can i possibly fail by getting a place of my own? i don't understand the reasoning behind my dads logic, but somehow i need to grow up and do stuff for myself, but not by getting a place near campus and being independent. somehow he thinks that school is some holy ground that will protect me from every horror that is grown up life. sorry dad, but sex, drugs, and alcohol still exists even in dorm life. and as of staying home. . . it's just not gonna happen. i still don't understand why a man would rather take out a loan to buy a car and gas money(cuz i'm sure not paying for that much gas)instead of letting their daughter get an apartment for free thanks to the u.s. education department. so i have to ask, when is it time to let go and when is it time to grow up? as kids grow into adults is there a magic point when they know all they're supposed to know for life or is it all just how well they can b.s. their way through what life hits them with? i think every person is different and every person deserves a life that they can create for themselves. maybe it's just me but i think sometimes you just have to let go. sometimes that's really the only thing you can do.
