I want to add my agreement that this is a good website. The support groups and chapters can be very helpful. I attended one for awhile and gained insight into my anxieties at work and other feelings and behaviors.

Here's a book suggestion for your partner or family members to read:
Loving someone with bipolar disorder, Julie A. Fast, John D. Preston, Psy.D.
It is written for the partner or family member but it may also provide insight into relationships.
