@SusanEllen66 I’m glad that you have found a medication regimen that helps you! I’m sure narcolepsy 2 can be difficult to manage.
You are correct there is Bipolar I and II. There is also cyclothymia. And then I think there are people who are sub-threshold for that, who do not meet criteria for a diagnosis, but may still benefit from interventions that are helpful for people with bipolar.
Here is the link to the Mayo clinic page that describes cyclothymia.
I have bipolar 2 and I think it’s important to note, as the website does, that Bipolar 2 is not a milder form of Bipolar 1, but a distinct diagnosis with different management strategies.
Best to you!
