I Use to Live In a Bad Neighborhood

So I picked up some bad habits. Some affiliations and I fought a lot. I live in a better area now but it's still not the best. Back at my old neighborhood I picked up the habit of carrying razors in my hair, an open switch blade in my pocket, a mini knife in the fold of my bandana, and small razors from a shaving razor in my mouth against my gums and lips. My fists are always clenched. So by this description I'm sure you can see why everyone thinks I'm a sociopath. Very few get to know me for who I am. I am a nice girl who walks with confidence. I don't start things but I dont back down. I get good grades. The only issue is my home life. Wish I could make this stop.
