Like the others said. Your T is not a doctor.

NO hypomania does not automatically escalate to mania. I've been hypomanic many times and it did not turn into mania. And what if your hypomania last 6 days instead of 7. It's just an arbitrary cut off used for diagnostic purposes.

Also there is rapid cycling. I've experienced severe depression and hypomania with a 24 time span.

What he's saying about the antidepressant induced mania is flat out wrong. When a depressed person takes an antidepressant and they get mania. That's a bingo! It indicates that the depressed person is in fact bipolar, but spends a lot of time depressed.

I would give some serious thought to finding A new T or Pdoc. Of course you don't WANT to be bipolar. But if you are and don't receive adequate treatment it will lead to a great deal of suffering.
