Thank you, Muffy and Capp,
Yes, Capp, I do realize that much of this has to do with going off this insidious medication, and that, yes, in my past of taking such meds for 17 years, I was simply oblivious to things that seem offensive to me now. On the one hand, I don't like being this way, as negative feelings are so debilitating to me, while on the other hand, I also recognize that I am processing interactions with people differently, and often not so well.

I don't like offending people, and will go to great lengths to apologize and take on blame myself to appease people. I suspect there are a lot of people here on PC like this. I've been this way from childhood onward, and bent over backwards for others, who, in reality, would rather not have dealt with me at all.

Also, in trying to think about this objectively, there is no hard and fast rule that siblings have to be close and share the picture perfect Christmas. I have been living with some sort of delusion about my relationship to my sister, which, in reality, was never a close one. We grew up fighting, actual physical fights, in which I was always the one injured but also the one who had to make amends. I'm in no mood to approach her now with an apology of it being my mindset, of being flawed, of being the emotionally unstable sister coming off meds, etc.
Sorry, I'm rambling.

I just want to add here, that PC is the only place where I can assess all of this. I'm grateful for my PC "family."
Love
Patty
