It is okay to vent. Sometimes doctors can be pretty crappy like this. Since you don't feel the evaluation went well I would recommend getting a second opinion. I was unaware that cyclothymia was dropped from the DSM-V.

You will also find that different doctors will diagnose differently. You might receive a Bipolar 1 with Psychotic Features from one doctor and another might diagnose you Schizoaffective Bipolar Type. It is just one of the qualms with mental health. That's why in my opinion the best doctor will treat symptoms once they have an established working ground.
