NAMI will help you a lot. I suggest study everything you can get your hands on about the disorder and talk with both consumer and family at these NAMI groups because they can help you more then most can to understand and be prepared for another crisis.
It will take time for her to come to terms with being bipolar. It is a lot to deal with. My husband told me once after his diagnosis that it was not fair to learn the extreme amounts of energy he loved were part of his illness and not part of him. He worried that things he thought were part of his personality were going to go away with the medication. He was sad that "there was something wrong with him" for weeks after he was told. He still hates it and avoids telling anyone because people are very in to believing the myths and stigma of "mental illness". I too have had my fair share of the uneducated judgment. Once had a coworker ask me if I was afraid my H would kill me and the children


........but I am now just going on and on.
I would suggest going to Family counseling (instead of MC) because there are going to be new dynamics to your family life that you might want help getting through and making changes that help everyone. Build your self a support system.
Like I said before to understand what your wife wants you will have to pay attention and when she is level ask her.
