She refuses to help around the house in any way including picking up her own trash. There is a history of bipolar disorder but she refuses to take medication. She constantly tells me I'm a "peice of crap mother". I don't deserve this either. I finally threw her out at age 19 and she now lives with my mother. I fear for her future and wish I could have a normal relationship with her. She is so difficult that within minutes a nice conversation turns ugly. She finds a reason to become angry with me. What is wrong with her? This doesn't sound like bipolar disorders I've read about. She never has highs it's only fury and sorrow. Please help,
