12 going on nearly dead

I don't like to remember this.
I don't much want to think about it.
My life was very affected by this still I will make a long story short.
I was 12, as innocent a girl as anyone could imagine. Dolls, cute dresses, daydreaming about being a princess, yes, even at 12, I was a slow bloomer.
I was walking home from school.
Someone threw a small liquor bottle at the back of my head.
I kept walking, holding on to a soda can.
Another bottle was thrown at me, I turned around and saw two boys, skin color doesn't matter to me but yes they were black boys. One was on a bicycle and one was on foot.
I tried to ignore them but the boy on the bicycle rode his bike up to me and cut me off with his front wheel.
I was taken aback, "if that makes any sense" my arms went up to avoid being crushed between my body and his.
My soda can spilled a little on the boy. Boy the size of a large man.
I don't know what happened, how I ended up on a busy road with traffic stopped being beaten over and over and over and over.
I looked up pleadingly, I couldn't speak, the kicks to my back, my side, my head were coming so fast I couldn't do anything to protect myself.
I heard his friend plead with him to stop, but when I looked up I saw that I was a circus. A circle of people were just standing there, a whole group of people who could have helped me were just standing there, just watching him beat on me, on a 12 year old kid!
It went on for what seemed forever.
Finally someone, not of the circle of idiots, someone from a store nearby called out, he must have mentioned police or something because the boy got on his bicycle and rode off.
I don't know how I made it home.
No one came to my aid
I got home, some how unlocked the door, some how called my mom, and I remember nothing after that.
Only weeks of police, lawyers, being humiliated at school when I could go back, still black and blue.
My hair was cut funny because it had to be removed from my swollen eyes. I couldn't see, I hurt everywhere.
Millions of questions, being pulled out of classes for interviews with more and more police.
Pictures, I can't go on, I'm too upset.
I have a daughter now and the one thing I promise to myself is that she goes to learn some martial arts, to learn how to protect herself. My daughter can chose everything else, I will never force her other things that she doesn't want, but I need to know that she could protect herself.
Unlike the circle of idiots, I never stand aside and let the weak be beaten on.  Not people, not animals, nothing.
I will jump in and attack if I must, but I will not be a standing idiot letting a poor child be beaten near death while I watch. I should have sold tickets.
Those ---------, idiots!!!!!!!
I realize now that what hurt more than anything was not the one boy beating on me, not the pain from the beating, but the way in which I could trust no one to save me. Having no faith in people can become very lonely. I am glad, now, to know that there are people who would come to my rescue but for years I felt very alone.
