A. - first of all let me say, AMEN! I totally know what you are going through. But, being 2 years further into it, my advice to you is Just Hold On! It gets better.
Let her have her space while you make sure she isn't making bad choices on how to use it (myspace, IM, etc.). Believe it or not, teenagers brains are going through a major restructuring and look alot like a toddlers at this time. Scary thing is their "toys" and "choices" have alot higher stakes. Just like you would keep toddlers away from stairs for their own safety, you have to keep teenagers away from things that could hurt them long term. I'm raising a 16-year old on one end and a 3-year old on the other end. I find myself using alot of the same techniques with both. Efficient!
Here are some hard earned teenager tips:
1. Consider whether they trust YOU instead of whether you trust THEM. They have to feel like they can come to you without a blow up or lecture.
2. When they DO come to you, as long as it isn't something immoral or illegal, ask first, "Do you want some feedback from me?" before offering your opinion. They need to see you trust them to handle their own business.
3. Be their safe place to fall. Handle their mistakes with the gentleness you hope others handle yours. That does not mean that you can't deliver consequences but they have to be natural and fair.
4. When they are rude, offer them a chance to try again. Make sure you are always using YOUR "please"s and "thank you"s with them. PLEASE unload the dishwasher. THANK YOU for hanging up your coat. Not saying you do but lots of times parents complaining of rude children are pretty rude to them too.
4. Take a look at the RULES in your house and make sure they aren't excessive. Divide into negotiable and non-negotiable. The non-negotiables should be very few and have the most severe natural consequences (sex, drugs, alchohol etc.). Look closely at the negotiables and see if you are setting your kid up to fail by having unrealistic expectations.
5. Ask yourself if there may be some rules in there that are breaking down your relationship with your child and whether or not it's worth it. For me, it wasn't worth it that my daughter couldn't slam her door. So we let her and it didn't continue because it wasn't getting her desired effect from us - continuing the battle. One time my daughter told me one of our rules was stupid. Upon further review, she was right. You don't want to be in that situation - be proactive!
6. Take the remaining RULES and turn them into PRINCIPLES. Maybe you have lots of rules regarding your property (no eating on the sofa, no wearing shoes in the house). That principle would be: We respect our belongings. Makes it a big positive rather than a million little negatives. We are Christians so we add that we believe everything is a gift from God and we need to be stewards of that gift. You can put your family faith or values into it or not.
A basic principle in our house is - and has been for several years now - "You show me in this house how you will behave outside this house". If I see good attitude and respect for authority/rules, then I can feel comfortable turning you out on to society. If I don't, then I have a duty to the public to keep you in this house :).
After all that, let me tell you that, for the most part, our daughter is now (at 16) not yelling, fighting, slamming, ignoring, sassing, etc. She has chosen (FINALLY) good friends and has a nice boyfriend. She is working and getting good grades and being otherwise responsible (curfew, phone minutes etc.). Over a year ago, I wouldn't have predicted it but so much can change in a year.
I repeat, JUST HOLD ON!
