Before I start, I just feel the need to say one thing. I understand that you feel emotionally compromised about what's happening right now, but when you explain things to people be careful not to overindulge in some of the "poetic" phrases you decide to use. You don't need to tell us about the "darkness of your life" because some of us have lived it. If what you're saying is real, we'll get it.
I can understand how you feel, somewhat. And despite
>>2's good intentions I can assure that sometimes the authorities aren't the best option. So I would first say you need to assess your situation more, since what you've posted seems wholly emotional in context. For example, if you haven't made a plan, you might as well go home now. Leaving because living conditions are unbearable is one thing, but leaving because someone upset you is childish. You step out into the world thinking that anywhere is better than there, but unless you've got somewhere to go and nothing to go back for, you'll find yourself in shit before too long.
Of course it had just occurred to me that while it may seem snobbish of me, I'm not going to lend any help beyond what I've stated until you've proven to me that you've put real consideration towards your actions. Simply, the more I see your post, the more a see a child running away because his parents are mean to him, than a man who has really taken all he can bear.
