No, just no.
Don't even consider this crap for a second.

Running away is not only beyond insane, it's illegal (border crossing, plus without a supervising adult??). Not to mention extremely dangerous. Heck, you could be kidnapped, get lost, robbed, run out of food/water, etc, plus, from your description you don't even seem to know the exact destination you're headed, or how you'll get money. You wanna be a hobo or something?

And of all places you choose to run away to, why oh why New Jersey? I mean, really? NEW FREAKING JERSEY?? I live there, and I personally do NOT recommend it. First off, it smells. We've got gangs, sex offenders, psychopaths, and some of the most dangerous cities in the US. No, you do not want to be here, unless you want to die lol. If you want to run away somewhere safe and crimefree, try Canada. xD
If you're being "abused" by your parents as you say, I suggest you call the police or something if it's really that serious. Otherwise, suck it up >.> As for not having any friends.. well, sorry but you're just gonna have to live with that.
