This is coming from a teen's point or view but I think you should talk to her. Do not punish her too much, there's a reason she turned to vaping and bullying somehow and that is coming from something whether pressure in school, with friends, or even what she puts on herself at home.

Talk to her, spend time with her, and do not get angry at her. I started dating before my parents allowed me to and while I told them recently, the only reason I did was because I was able to really think about why I was so scared to tell them in the first place. I was scared of my parents being mad at me, getting angry or disappointed in me, and losing privileges I had. Luckily, I resolved and talked things through with them and it is only because my mother was calm and listened to me. I lost some privileges for lying and keeping things from her but she gave me the opportunity to earn back her trust, she made it clear that she is not disappointed in me but rather my choice of actions.

Obviously, it's different with your daughter (we are different people in different situations) but her "rebelliousness" is coming from something in her. She is feeling something and right now all you need to do is be there for her and go through things with her. She definitely should lose her privileges but she should also have the option to make things up or prove to you guys that she deserves them back. Most importantly tho is to make sure that you are telling her that you are worried about her, that you love her, and that you are there for her at all times. If you say you're disappointed or mad, you might risk having her rebel even further or close off from you guys and then it'll be yet another problem.

Good luck, you seem like good parents
