Well, imo, in the scheme of things, that's the best symptom NOT to have!
This is a tough dx in that it's really an "in between" type disorder...but that you have certain states of moods and such... yes I can see where that can cause
fluctuations in moods and feelings and attributes.
I think the first thing, that is simple but not easy, is to allow yourself to be changeable? Then, if you can try and realize WHEN at what times or situations might you need to be more aware and on guard against becoming irritated (and irritating others?) so you can prevent or limit this reaction, that might be good too.
Good wishes, and welcome again
