Im sick of living in australia. hitting breaking point.?

I'm American and I've lived in central Australia for a looong time. It was ok until I got to high school. The people here are horrible to Americans. I'm a bit different to most people. And they treat you like **** if your not like everyone else. I know I sound like a ***** but I've never done anything except try to be friendly. The only time I ever insulted someone was one guy who randomly looked at me and said go die ***** and shoved me cause I was friends with his ex. people insult my accent and say things like "haha Americans wouldn't understand" "oh look, she's yanking again" "americans suck, go aussies!", spread rumors about me (most ppl who add me on fb is to see of a story was true). All my "friends" now shun me when I try to talk to them. I have one friend who is great but she believes everything she hears about me and before asking me about it ahed tells other ppl, particularly my ex who is good friends with both of us then he yells at me and won't listen when I try to tell him that its not true. No offence to the aboriginals, most of them are ok, but the ones here are drunks, rapists, lazy *** druggies, murderers and whenever they see a white person they yell, call you names, grope you when you walk past, I can't ride my bike or walk to school cause a lot of times I got jumped and had stuff stolen. Look, I know I sound horrible but I'm honestly saying that I have never done anything to deserve all that. When I make a mistake I go to full length to make amends.I'm not trying to insult the place but god I can't take it anymore! how do I cope til I can move back when I turn 18? I'm 16 now
