there are three main mood disorders that dont include schizophrenia: they are:
cyclothymia
bipolar
dysthymia
now, i have dysthymia: thats a mild form of bipolar, but without the hypomanic episodes, and is instead a constantly low mood.
bipolar, well, youve probably looked it up already.
cyclothymia: "Cyclothymia (pronounced /ˌsaɪklɵˈθaɪmiə, ˌsɪklɵ-/) is a mood disorder and a form of bipolar disorder. It is defined in the bipolar spectrum. Specifically, this disorder is a milder form of bipolar II disorder consisting of recurrent mood disturbances between hypomania and dysthymic mood. A single episode of hypomania is sufficient to diagnose cyclothymic disorder; however, most individuals also have dysthymic periods. The diagnosis of cyclothymic disorder is never made when there is a history of mania or major depressive episode or mixed episode. The lifetime prevalence of cyclothymic disorder is 0.4-1%. The rate appears equal in men or women, though women more often seek treatment."
it sounds like you could have cyclothymia
symptoms that stand out (for all three): hyperactivity, quiet moods, sudden violent outbursts, speaking very quickly, low moods, unable to stay focused on one thing
