Thoughts on turning seventeen, (one year until I'm an adult!)

In exactly one month I turn seventeen, which is really scary for some reason. I don't think it's that I'm turning seventeen, (being born in December its never cool turning anything, because a few weeks later people are turning one year older than me again!) I think it's because three weeks after I turn seventeen my best friend turn eight teen and that is a scary number! I'm not ready to be an adult. I know that there are many things that are fun by being legal, I can vote, drink, drive a car, but the thought of all the expectations people have. I haven't even finished eleventh grade, I'm not ready to be an adult!! I'm afraid that I'll still be sick and rely on my parents when all my friends have moved out and gotten jobs. I know that most people don't move out from their parents before they turn twenty, but eight teen is a big step closer and that scares the shit out of me.
