No. What's done is done for the most part.
Either you have a really rough road ahead of you for a long time to come... because of her choices.
Or
She'll decide to take a step back from the peer influences, rebellion, and typical stupid teenage mistakes... because she's chosen to.
Eventhough the ball is in her court now...at this age and the years to come, that doesn't mean that you get to stop being Mom.
Sometimes being the Mom is just not fun at all.
Keep on doing what you've been doing. It sounds like you've been doing well so far and you probably still are. You're teaching her to respect authority, you're there for her when she's receiving a consequence, you're giving her consequences, and you're probably being consistant about it.
Did you know that it's not always the parents fault? Great parents who are loving, educating, attentive, caring, supportive, and wonderful in every way, can have kids that just plain 'ol make bad choices. She's old enough now to make choices on her own with quite a bit of knowledge about what she's doing... The sad part is that she is still a child and she still doesn't have FULL knowledge of what she's doing. Teens/children can sometimes get themselves into pretty heavy consequences that are clearly over their head and over their comprehension. That's the scary part. That's why the grown ups need to keep into perspective that if she's acting childish, well that's because she is a child still. She may be doing big bad girl behaviors but, she's still a kid.
From the police officer to the school principal, all of these people should be able to keep that perspective. They work with lots, and lots of kids. Some who are smart, yet nieve, like your daughter... some who are evil to the core... and some who are just plain stupid and will not "get it" for a long time. Out of all of the people she could have gotten herself in trouble with... it seems to me like these mature, individuals, have been placed in her path for a purpose.
Thank God, she didn't do something obnoxious to some freak, lunatic, with rage problems... Although she was irritating as all get out, all of you have the capacity to demonstrate self control and sturness when it comes to your anger and frustration with her.
She has been screwing up... But, it seems like God has given her some pretty soft places to land.
Well, I hope that you don't have a rough road ahead of you.
If you do...
You may end up becoming the "hated one", the "punisher", the "consequence giver", and you may be told that you don't HAVE TO BE that way (as if teenagers have any place giving parenting advice about themselves).
But from one mom of a teenager to another, all I can say is if I had a dime for every time I've said, "Yes, I have to be this way because I AM the Mom (not you) and I happen to love you so much that I can not allow this destructive behavior to continue. You deserve better than what you're getting yourself into; deary. So whether you understand me or not... and whether you agree with me or not... you are still grounded (or restricted) from the computer (or whatever)."
Teens seem to never understand, or accept the consequences of their actions and we, as parents, end up wondering (for years) if they ever "got" it at all.
