Hi anon331312,
The main pwBPD in my life is my H's kids' mom. While this Christmas was uneventful (eerily so), I think I do remember one Christmas where she wanted H and I and the kids to come back into town early from our own Christmas trip... because she just had to do a tarot reading with the kids.
...
That sounds stressful to cope with BPD meltdowns around a holiday. I wish it were less common to hear about

Have there been any aftershocks since then?
Any chance to do some self care and give yourself a break from the drama?
