I go back and forth between accepting my diagnosis of BPII and thinking it's more MDD.
My hypomania is so rare now.
Yet, in truth, I have had some hypomanic episodes, so that qualifies me for BPII. The stubborn depression helps to confirm it.
Every pdoc I have seen over 40 years has ruled out any personality disorder.
If you have not been formally evaluated, do ask your pdoc to rule on any condition you suspect may play a role in the entire picture.
