I know how u feel, I guess I'm too old to runaway now tho, I;m 19, but about 4 months ago , I seriously thought for the first time about moving out, because I'm just tired of living here with my family, Its just a thought though, I won't be able to move out for at least another year tho, til then i'm stuck here.

sometimes we have to run away from ourselves..forget everything..just us and our thoughts
youre a teen its normal
everyone of us goes thru that stage
be still and be strong
say what you want and what you feel
do something that makes you happy

I congratulate you. It takes a lot for a person to admit what they truly are. I can empathize with you in the sense of feeling trapped and possibly hating everything around you, being selfish is just an aspect of humanity. The best advice I can give is to find something...very clear and precise right. I'll give you an example. I am not telling to do exactly as I did but follow the same thinking. I hated everything about my former life (I call it the horror, teen years are dangerous) and wanted to escape. I went to a counselor...basically a therapist and she listened to what I had to say and suggested that I tried everything. Really? what good is that? If I hate everything how can I find something? What she said to me is that if you find something, even something you hate, which can distract you long enough perhaps you may find something you like somewhere you haven't looked before. So I did everything, during high school I joined the swim team, debate team, a thing called Link Crew where we help integrate freshmen into the high school environment, play video games, hiked, read, wrote...a lot of stuff.
In the end I got distracted long enough to get an understanding of what I like. I found out I love reading and writing. During all my distractions I came across the ROTC program at my college. At first it was just a diversion but now I am sold. I love everything that has to do with the United States Army because even if I am not the best out of everyone I have done my best and it makes me feel good. I have decided to join up and serve my country solely because it makes me feel good. I can go with the "Sunday school answer" of: I do it for pride, honor, and a sense of duty but at the end of the day I just do what I do because it makes me happy.
I am not saying you should join the Army or whatever but literally do everything and anything. You will never accomplish everything so you have an infinite list of distractions. You get bored with one you have got millions of other things to do.

That's the advice I got and here is a small question for you: Why the city, what exactly draws you there besides the sea of faces?

ALbeit,sorry to hear that you have to hang around there for another year or so, that made me think though, my brother recently moved out and i wonder if me wanting to leave has something to do with that.
yourethevoice, thanks heaps, your words are really encouraging (not as in encouraging me to run away, but just generally encouraging lol)
MoeMDB, i cant really be sure what it is about the city. probably because its far away from where i live but i still know it fairly well. im pretty familiar with it and i know my way around. but yeh, mostly just being another person in a crowd i think, but also i like watching the world go by and in the city there is always something going on, i like seeing all the different people and wondering what their lives are like and where they are going. i dunno...it just sort of appeals to me...
