My wife has an officially undiagnosed mood disorder.  With all the research I have done BPD is as a very good match. I'm not a doctor obviously. How can I help my wife see the problem? I want to get her help. On her bad days she hates everyone and every thing. She says she is tried of me and sorry she married me. Nothing you can say or do on these days will change her mind. I tried to talk to her last night during one of these times. I asked her several times why she was upset with me. finally she said "i don't know". I was hoping she might start to understand. 20 minutes later shes somewhat OK, then she swings the other way. On her good days she tells me how much she loves me and how good I am for the family. if you try and talk about the problem she just laughs and says "its OK" and walks away. She isn't violent or trying to hurt herself, I cant have her locked up, what can I do to help her to understand that there is a problem. How can I encourage her to seek help?  The back and forth (I love you I hate you I love you) is very taxing.
