Luckily, your daughter sounds intelligent and capable. If she botches high school, it will be fairly easy for her to engage at the community college level and move on to university.
In my family, alcohol and codependence were the only coping skills we were taught. So as teenagers, trying to be functional and fit in, we were lagging behind, bright or not. There was stuff we just didn't learn in an A home. It made school stressful.
Where can we send our kids to learn that stuff? Maybe al anon, maybe a teen group, maybe volunteering or service.
I learned a lot through my weekend jobs. Important stuff, like how to get along with people I didn't like, to show up on time, sticking to a scheduled shift, budgeting, that I never learned in Chemistry and certainly didn't learn at home.
teenagers aren't easy on the best of days. I am sending you a big big hug! whatever you do for your daughter, don't forget to do something nice for yourself, too!
