Iris's symptoms suggest a persistent pattern of depression that has lasted for more than two years. This is consistent with the diagnostic criteria for persistent depressive disorder, also known as dysthymia. Bipolar I disorder and hypomania are unlikely because there is no mention of manic or hypomanic episodes. Cyclothymic disorder is also unlikely given the absence of symptoms of non-depressed mood.
