take it a step futher, Remove her bedroom door.
I had seen this on Scared Straight that first episode for
that one preachers daughter who kept getting into trouble.
I'm sorry but taking away her "toys" will do little good, I grew up
with girls like these & all they do is laugh.
I would contact any agencies like social services to get suggestions.
Also keep a watchful eye on her bedroom window.
Why?
I was young once and one thing I know for sure? No matter what the generation? All teens love sneaking out that bedroom window.
I know I was young once & I also had friends that did this.
You must let your 17 year old know that YOU DON'T PLAY.
I hope this helps.
Also when you feel ready head to your nearest family counseling center for yourself to get some resolution for whats going on at home.
I wish you all the best.
Keep me posted my friend!
