I was always dx with a mood disorder since I was 15 years old. I spent some time in the mental hospital at 15.
It always stayed "mood disorder" because I'd only go seek help when I was depressed. I'd go hypo and stop treatment. This went on until I was 20. I fell into a psychotic depression and seeked helped. A few weeks later I went in, told my T I stopped all meds and was cured over night. I was then dx with bipolar 2. Of course I did my ritual in quitting treatment. But it was the first time I ever went in while manic.
