Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.

This link is from NAMI (national association of mental illness)....they are a support group, you could look up in your area for information and help...the site also goes into a good bit of detail about bipolar. https://www.nami.org/Blogs/NAMI-Blog/February-2017/Loving-Someone-with-Bipolar-Disorder
This link is a book that could be helpful, for both of you. https://books.google.com/books/about/Loving_Someone_with_Bipolar_Disorder.html?id=xtYePT0ZpMEC&printsec=frontcover&source=kp_read_button#v=onepage&q&f=false
From my own perspective and illness...."""The Number One Person"""you'll need to focus on is YOU. Why? If you become so overwhelmed with the symptoms, start to let go of taking care of your self, then ya got two sick people....Best to you!
There is a group here for Friends and Families of Bipolar and I'll give you a link to it
