I totally agree with what MM just said.

IG, it sounds to me like it's emotional dysregulation.
Like others said, it could be from BPD traits.

The important thing to watch for, imo, is escalation; that is when you'll really know if you need a change in treatment. Otherwise, if you go to a psychiatrist, they would likely put you on mood stabilizers whether or not it's from bipolar or borderline or anything else. I'm not sure about the Sui as being escalation from a BP perspective, but maybe it would be a good idea to get another evaluation?

I have had many 'bipolar' episodes over the years. Racing thoughts, dysphoria, hypomania/euphoria, hyposexuality, flights of ideas. So many mixed moods too. I always think I am getting some type of psychosis, but never do. T says even with bipolar, there is emotional triggers, but it is more subtle. The more and more i learn about this stuff, the more i agree with the psychoanalytic views...

So if I went to a psychiatrist, i'd probably be dx'd with bipolar II, as that is the one that seems to be a catch-all for those with these mood issues when caused by PD traits. But for me, I think i have more histrionic-dependent and BPD traits than anything else. And I think why would I want to take lithium or Depakote for the rest of my life? I think when meds can really help people, it can be amazing, but that's not how it is for most people.

So I should add that CPTSD symptoms give me emotional dysregulation too. The emotional memories/re-experiencing is so destabilizing....

Just some things to think about.... I'm glad you are doing better than the weekend. I'm quietly cheering for you.
