Bravo momma. Nta. You’ve done(from what I’ve read) exactly what you should be doing. You took her to counseling(A++++++++ for that. Most parents wouldn’t even bother) you’ve tried a lot so far and at 17 she knows how to act. She’s damn near an adult(in the govs eyes) but she’s a child as well. Keep her in counseling so that your daughter and the therapist can work on her issues. Maybe even resolve them. Maybe try family counseling, just you your husband and your daughter. and try to get the air cleared. Maybe your daughter feels like she’s being replaced. Both her parents got remarried and had more kids(I assume your other children are step children) but you all gained kids and that maybe left your daughter wondering who will love me now that mom has new step kids and dad does too. You’re doing an amazing job at trying to juggle your daughter and keeping your family together. I would suggest family counseling and see where it takes you because she just sounds like she wants her parents back more than anything.
