I have a teenager that has been diagnosed with ODD, Bipolar, ADHD. She has been to psychiatrists, counselors and has spent time in a behavioral health center. I am struggling with how to get her to take school seriously. She seems addicted to talking and attention. She thrives on talking on the phone within class and on social networking sites. She is never on time to class and is failing everything. Her teachers are irritated with her behavior and are requesting she be removed from their class. She has already failed 4 classes from 9th grade and now she is failing 6 of her 7 classes. Always an excuse and always the teachers fault. Saying no or taking things away triggers manic episodes that are getting harder to deal with. Her defiant behavior is out of control. I have a 7 year old that is starting to mimic her behavior. I am a single parent with no support system. Father is out of the picture and no extended family to lean on. Please help. I just want my daughter to realize how important her education is before it's too late. Any advice would be appreciated as I feel like I am alone in this.
