It is good if you let those who you may have "ruffled" a bit if they are close with you, but not obligated, but respectful.
I do not go for any of us Bipolars using the unwanted behaviour and the disorder as an excuse for anytime you did have a problem with a person or ppl.
My brother use to get away with it but finally his pdoc set him straight and my parents too. Sure in extreme, out of control episodes (but with right meds one should barely have an uncontrollable episode) if any at all.
I hope I am understanding what you are talking about, so easy to misread people and posts when not face to face or not knowing someone.
Everyone is unique, mild mania can be productive somethimes, and when mild one person may be chatty and nice and then some may get irritable.
I think even non Bipolar people get this way, personally I hate when people think that means a person is in episode mode, gee, if we looked at everyone, their emotions, and behaviours we'd be able to DX the majority of people in this world as Bipolar, as well as many other disorders.
My suggestion, just be honest, with yourself and others.
Apology for an outburst is okay I think, and appreciated by most, my brother during his rough spots had apologized to me and family, and was sincere.
We pleaded with him to not decide to stop meds. cause whenever he would screw around, be noncompliant then it was almost a guarantee an episode would be coming soon

I don't know if I just amde any sense in reply to your post, but I hope some of it was informative in some small way.
I'm wishing you lots of luck dealing with this, it's frustrating at times and I sincerely feel for you.
Okay, you take care now,
