I agree with the above posters about not diagnosing your girlfriend, but at the same time I understand where you’re coming from. There is a lot of information on the internet about Bipolar Disorder- just research it. There are many misconceptions about it though. There are several different kinds of Bipolar Disorders. For example, Bipolar 2 is not as “extreme” as Bipolar 1.
It’s characterized by at least one episode of hypomania. May have a decreased need for sleep, become very social, are energetic, grandiosity, hypersexuality, however It’s not the same as mania as seen is Bipolar 1. They are functioning at full capacity, unlike people with Bipolar 1. They never show psychotic symptoms either.
Bipolar 2 Disorder is also characterized by at least one episode of major depression as well. The diagnosis for Bipolar 2 requires that the person never experience a manic episode, otherwise, they would have Bipolar 1.
Please remember that I am not a doctor, so the above statements may be wrong, but to the best of my knowledge they are correct. Please mods and admins, delete if necessary. -Vesna
