As a teenager, I was the incarnation of Satan, pure evil... I hated my parents, I hated authority, I hated anyone who thought they were going to tell me what to do. I even threatened to beat my mother to death with a chair if she did not shut TF up and stay out of my life. I had the chair raised.
From the age of thirteen I drank, did drugs, and porked (Ricks phrase) every loose girl I could find. I would sleep in phone booths all night rather than go home. I could fill a book on my escapades and by the time I was eighteen I was worn out, tired and ready to settle down.
I ran away from home at thirteen, but was apprehended and forced to go back home. I told my parents that I would pack my bags and leave on my 16th birthday, legally there was no way they could stop me, and I did.
For me, that was the day I accepted full responsibility for my actions from that day on. This was the beginning of me growing up fast. There would be no calling parents when the cops picked me up or when I got into trouble. I would go to jail if need be and face up to my choices. I wanted total control over my own life and this was the only way. Doesn't always work for every kid but it did with me.
Yes I found out quickly, how hard it was out in the real world. Made me that much more determined to succeed if for no other reason than to thumb my nose at the rest of the world just so they would not have the satisfaction of saying I told you so.
Those of you with problem kids, be grateful you did not have me for a son! But what I'm getting at here is, as bad as it may seem, there is always hope that your kid can eventually turn around and see the light. Not all is lost. If I could straighten out, then so can yours. I was written off by everyone to either end up dead or in prison before I turned eighteen. Could have gone either way.
As parents we coddle our kids and want them to have everything they need, but that's not always enough. Sooner or later they are going to learn that life is not easy. I don't think you can teach them too soon that life is hard. We all have to live by rules or else. Kids need to understand what that else is.
I would go so far as to see if your community has any scared straight programs. Because as a teenager, some of the mistakes made can be life changing or even fatal.
At her age she needs a serious case of tough love right now for her own good, but make sure she knows you love her. I hope it doesn't kill you in the process!
