The first place to look for bipolar support groups is via your GP or supporting social worker. Online one can look for groups on the Mind and Reach Out websites.
I could only locate one support group to meet your needs in Omaha. It is the "Depression & Bipolar Support" group, which is out of 6905 Blondo Street. Their number is (402)933-6326.
The most well known orginization would be the D.B.S.A.N.C.A. If you are unable to reach them you may try the N.M.H.A I could find no statewide list of bipolar support groups, but here's one for Spokane: http://www.spokesman.com/stories/2009/jan/02/spokane-support-groups/ . One place to inquire might be NAMI (nami.org).
There are many support groups for family and spouses of people with Bipolar disorder. You can use google maps to search for one near your location. Support groups are always nearby, consult with this source for one near you. http://www.dbsalliance.org/site/PageServer?pagename=support_findsupport
There are many online support groups for people diagnosed with bipolar disorder and their families. One such group is Daily Strength (http://www.dailystrength.org/c/Bipolar-Disorder/support-group). The Depression and Bipolar Support Alliance website has a search feature that allows you to search for support groups in your area (http://www.dbsalliance.org/site/PageServer?pagename=support_findsupport).
While there don't appear to be any bipolar support groups IN Thousand Oaks, there are quite a lot in CA. Check out the following website to find the one closest to you: www.dbsalliance.org/FindSupport (You'll have to accept the terms of use first)
Many churches offer support groups for different mental conditions. Check with your local church to see if they have a support group. Many hospitals have support groups for almost every affliction, disease, or problem you can think of. Call your local hospital, and if they don't have a specific support group for it, they can probably tell you where you can find one.
Many websites provide this information. One such site is http://www.dailystrength.org/c/Family-and-Friends-of-Bipolar/support-group.
In the links I've provided below, one gives information on bipolar disorder, and the other one is a search by state to find a support group that meets in your area.
No ignoring people is probably not one of the signs of Bipolar. It could me a sign of attention deficit disorder, or it can simply be a matter of insecurity or distrust.
One can find information on what causes bipolar disorder in humans by using websites such as Wikipedia or NIHM that tells you everything you need to know about bipolar disorder and how it is caused in humans.
There is no reason that one could not, so long as one is properly trained.
No not really. You can tell a bipolar person from another. Bipolar persons will go through many mood swings. The person can feel happy about something one instant and then the next they could be sad or depressed. I would know as my mother is bipolar.
