I had been diagnosed with Dysthymia (Persistent Depressive Disorder) in the past and was reluctant to accept the diagnosis. Even though I have spent most of my life dealing with depressive like symptoms, for some reason I refused to identify with the label completely. In the past, when a teenager and young adult, I experienced mostly depression and occasionally brief(~4 hr) euthymic/hypomanic periods. As I have stated in my about section, I experienced severe depression in the morning and euthymia/hypomania in the evening with quite a regularity. Many clinicians would describe this as diurnal variation in the context of a mood episode but I am not so sure.
