These are tough years.
I remember.
My kids are now 30, 28, and 24.
I have great relationships with each of them....we're truly friends as adults.
I remember the teen years, though.....and what works with one, may not be the best approach with another.
The one thing that I can say, that is ALWAYS good advice, is keep the communication lines open and make sure your daughter knows you love her no matter what. I remember one really tough time with my youngest......there was a wall growing between us, and I was feeling really desperate to break through.....and I remember telling her (and meaning it) that I loved her more than she could know, and she was a "part of my soul." It sounded a little unusual...and caught her by surprize, I think...but she (finally) heard me.
She needs to understand that you're a person with feelings and fears, yourself.....and you love her and will stick by her for all her life, no matter what. She needs to know that you're willing to do whatever it takes to be a true friend to her....that includes doing your best to keep her on the right track. Deep down inside, she probably knows that she can't say that about most of her peers, at this point in her life....although they are loyal enough right now. On the other hand, she's got to learn to be her own person and take responsibility for her own actions and decisions....apart from you. That's the tough part. Knowing how and when and how much to let go.....
Counseling is good. Also, it's good to know who her friends are.....although you can't control who she picks as friends, you can be familar with who they are, and not be a stranger. If you can welcome her friends into your home, and provide a fun/safe place for them to hang out....it's usually a good thing....
Hang in there. She won't be a teenager forever. Just hang on to the relationship during this trying time....
