We are at a loss here . Our 18 year old daughter has been manipulating her mother and I. We separated when she was young and she spent a significant time with mom and came to live with me at 14. She has always been emotionally distant, keeps to herself, diagnosed ADHD...A lot of trouble doing school work . She spends hours on end on discord discussing disassociate identity disorder and has diagnosed herself with this . We have tried to get her help . She constantly says we do nothing for her , she won’t do school work , won’t do chores and won’t get a job . Everything is someone else’s problem or fault . She decided to move back in with mom and refuses to talk to me . She wants to quit school because it’s dumb . I’m not sure how to help her but she’s been terrible to her mother and myself as well as her step parents . She is burning every bridge . Any advice?? She is constantly playing her mother and I against each other and is driving us both crazy.
