I saw that, but I figured a 3 year old R rated Australian documentary was a poor candidate for notebook and backpack merchandising. 
It’s not Australian, it’s a US film about a US school. Don’t know why IMDb has the Australian release date up top.
So it is. Weird.
Sorry, I’ve only just skimmed over some of the thread, but I’ve been thinking about the OP.
I think the answer is that you need to model the behaviour you would like to see.
That means, if you wish her to be respectful to you, you must be always respectful to her.
If you wish her to be honest you must strive to be plainly and consistently honest with her. If you don’t want yelling and screaming and high drama you must never do so yourself. If you want her to be considerate of your feelings you should always demonstrate consideration for hers. If you wish her to resist sarcasm and hyperbole, dramatizing conflicts and making a volatile situation worse, than you must be capable of demonstrating restraint the same way. You must be even handed and fair, and willing to listen. Consistency, stability, ride out the rocky years.
Everyone recognizes this is an extremely tall order, you certainly deserve credit for stepping up to what will no doubt be a challenging relationship. I read somewhere that the most complicated relationship on earth is Mother - Daughter. You’re not doing anything wrong, because it’s rocky or conflicted, difficult or stressful.
Give her some time to adjust she’s been through a lot, and it’s an unstable period of life with a lot of change to start with, but I’m sure you’re aware.
Anyway, I wish you lots of luck, remember life is messy and the hardest things in life can produce the most surprising fulfillments.
