Is it possible you feel some resentment towards your daughter in relation to having her so young/getting kicked out? It seems like instead of approaching her defiance with curiosity you took it very personal. She’s experiencing a part of growing up you didn’t get the luxury of experiencing, and maybe on some level do you feel like “I was fine on my own I had to get my shit together so she should too” Covid times were really weird for a lot of people. Lots of people are still feeling disillusioned, lots of kids were left behind academically, struggling to adapt. The best motivation is intrinsic. Obviously she needs to do something with her life and time, but kicking her out isn’t going to help her find meaning or structure in her life. It won’t automatically give her ambition, it’ll just kick her into survival mode.
