Yasmine, I'm very sorry to hear what happened and thank G-d you're alright.
I must agree with others that say NYC is, for all intents and purposes, a jungle and you should leave. It pains me to say that since I grew up there and lived in Queens for 33 years but it has gotten progressively worse and there is no turning back. I remember about 28 years ago a black animal tried to mug an old man in my neighborhood who was out walking his dog. The old man began yelling and within seconds about 15 of us came out of our homes, chased the mugger, caught him a few blocks away and held him until the police showed up. When the police showed up this vile, disgusting excuse for a human being immediately ran up to them and began complaining that we had held him at gun point, asking and expecting the police to arrest US! Instead one of the cops came up to us and said "This guy says you have a gun. I don't care whether you do or you don't. Thanks.", walked away, put the handcuffed beast in the back of the police car and left.
That is what I expect from decent citizens and police officers. The animals who attacked you and the bystanders who didn't help you are cut from the same mold.
