I was diagnosed with bipolar NOS about 12 years ago, but I was for the most part unmedicated. Looking back I had periods of depression lasting about 6 months and hypomania - maybe bordering on mania - lasting about 3-4 months. So basically I think I exhibited BPII symptoms.

Then this year changed everything. I had two psychotic manic episodes, and now my diagnosis is BPI with psychotic features. I also had several severe depressions with psychosis. I think I've probably had some tiny bits of psychosis before this year, but nothing so extreme as this!

Has anyone else experienced a change in bipolar type over time? I don't mean misdiagnosis; I mean changing symptoms.
