I agree with Elvive and SueDomin that you are a parent not their best friend. I feel so sad when parents off load their troubles on to their children. I've seen loads of that on tv programmes and such a shame.
Coming back to teenagers from hell, I had one too. Had a mouth as big as a barn door. If I said something was white, she'd say it was black. The doors used to vibrate with the bass on her upstairs Hi-Fi. I'd go up and turn it down and then she'd turn it back up. She was in a group of school friends who were just the same. Mums used to knock my door, A..'s done this and done that. The group broke into the youth club hall, shoplifted, got arrested for drunk and disorderly, got expelled from school just 3 weeks before she would have left anyway. Plus a whole lot more. I was divorced but I do know she wouldn't have dared to behave like that had her dad had been here. I wouldn't go through those years again for a million pounds! Here's the positive, she finally left home and guess what, I'm so proud of her!. She has a well paid job, buying her own home which is a nearly new build and gorgeous. So tidy ( I used to pick everything up for her because I couldn't stand the mess, wet towels left on the bed, hairdryer, clothes etc. Times I used to threaten to throw them out of the window.) I should have! Getting back to the point, She owns her own car, goes abroad every year on holiday. We go shopping together.Spoils me at birthdays and Christmas although I tell her not to. We are very much alike in that we both like to be boss and independent women and clashed when she lived at home. She still has a gentle telling off sometimes. When living at home I used to tell her that for as long as she lived in my house then she abides by my rules and when she got a house of her own she could do what she wants. She still rebelled!
It will all work out Campaspe. You will get your daughter back again. Let her learn by her own mistakes within reason because no matter how many times you advise them what to do. They will always do it their way. Good luck in putting up with the terrible teens.
